paragraph_text: Based on a mark in an interior chamber naming the work gang and a reference to fourth dynasty Egyptian Pharaoh Khufu, Egyptologists believe that the pyramid was built as a tomb over a 10 to 20 - year period concluding around 2560 BC. Initially at 146.5 metres (481 feet), the Great Pyramid was the tallest man - made structure in the world for more than 3,800 years. Originally, the Great Pyramid was covered by casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

paragraph_text: A food pyramid or diet pyramid is a triangular diagram representing the optimal number of servings to be eaten each day from each of the basic food groups. The first pyramid was published in Sweden in 1974. The 1992 pyramid introduced by the United States Department of Agriculture (USDA) was called the ``Food Guide Pyramid ''. It was updated in 2005, and then it was replaced by MyPlate in 2011.

paragraph_text: The Masonic Building, located at 296 to 304 Walnut Street and 456 to 460 Newtonville Avenue in the village of Newtonville, in Newton, Massachusetts in the United States, is a historic building built in 1896 as a Masonic Lodge hall. It is a massive four-story redbrick Renaissance-style building with a turret on the corner and a steep slate pyramid roof. The upper floors are still used for meetings of Masonic lodges and appendant orders, while the lower floors are used for retail and office purposes. The building was approved for listing on the National Register of Historic Places in 1986, but due to owner objection it was not listed. However, it was included as a contributing property to the Newtonville Historic District when that district was expanded in 1990.

paragraph_text: After his investigations Perring buried the robbers tunnel which remains inaccessible to this day. The pyramid of Userkaf entered the official records a few years later in 1842 when Karl Richard Lepsius catalogued it in his list of pyramids under number XXXI. Since Perring had already buried the robbers tunnel by that time, K. R. Lepsius did not investigate the pyramid any further.The pyramid was then neglected until October 1927, when Cecil Mallaby Firth and the architect Jean-Philippe Lauer started excavating there. During the first season of excavation, Firth and Lauer cleared the south side of the pyramid area, discovering Userkaf's mortuary temple and tombs of the much later Saite period. The following year, Firth and Lauer uncovered a limestone relief slab and a colossal red granite head of Userkaf, thus determining that he was the pyramid owner. After Firth's death in 1931 no excavations took place on site until they were resumed by Lauer in 1948. Lauer worked there until 1955, re-clearing and re-planning the mortuary temple and investigating the eastern side of the pyramid. Research on the north and west sides of the mortuary complex was conducted starting in 1976 by Ahmed el-Khouli who excavated and restored the pyramid entrance. The entrance was, however, buried under rubble in an earthquake in 1991. More recent work on the pyramid was undertaken by Audran Labrousse in 2000.

paragraph_text: The most famous Egyptian pyramids are those found at Giza, on the outskirts of Cairo. Several of the Giza pyramids are counted among the largest structures ever built. The Pyramid of Khufu at Giza is the largest Egyptian pyramid. It is the only one of the Seven Wonders of the Ancient World still in existence.

paragraph_text: Based on these estimates, building the pyramid in 20 years would involve installing approximately 800 tonnes of stone every day. Additionally, since it consists of an estimated 2.3 million blocks, completing the building in 20 years would involve moving an average of more than 12 of the blocks into place each hour, day and night. The first precision measurements of the pyramid were made by Egyptologist Sir Flinders Petrie in 1880 -- 82 and published as The Pyramids and Temples of Gizeh. Almost all reports are based on his measurements. Many of the casing stones and inner chamber blocks of the Great Pyramid fit together with extremely high precision. Based on measurements taken on the northeastern casing stones, the mean opening of the joints is only 0.5 millimetre wide (1 / 50 of an inch).

paragraph_text: The Pyramid of the Sun is the largest building in Teotihuacan, believed to have been constructed about 200 CE, and one of the largest in Mesoamerica. Found along the Avenue of the Dead, in between the Pyramid of the Moon and the Ciudadela, and in the shadow of the massive mountain Cerro Gordo, the pyramid is part of a large complex in the heart of the city.

paragraph_text: Userkaf's pyramid is part of a larger mortuary complex comprising a mortuary temple, an offering chapel and a cult pyramid as well as separate pyramid and mortuary temple for Userkaf's wife, queen Neferhetepes. Userkaf's mortuary temple and cult pyramid are today completely ruined and difficult to recognize. The pyramid of the queen is no more than a mound of rubble, with its funerary chamber exposed by stone robbers.The complex is markedly different from those built during the 4th Dynasty (c. 2613–2494 BC) in its size, architecture and location, being at Saqqara rather than Gizah. As such, Userkaf's pyramid complex could be a manifestation of the profound changes in the ideology of kingship that took place between the 4th and 5th dynasties, changes that may have started during the reign of Userkaf's likely immediate predecessor, Shepseskaf. Some 1500 years after its construction, the pyramid complex was restored under Ramses II. During the much later Saite period (664–525 BC), it was used as a cemetery.

paragraph_text: Greek pyramids, also known as the Pyramids of Argolis, refers to several structures located in the plain of Argolid, Greece. The best known of these is known as the Pyramid of Hellinikon. In the time of the geographer Pausanias it was considered to be a tomb. Twentieth century researchers have suggested other possible uses.

It includes space for government administration, a law enforcement complex, a performing arts complex, a child-care facility and structured parking. It also contains a single-story auditorium, a pyramid-shaped cafeteria and a cylindrical, six-story reception hall, as well as office buildings.

paragraph_text: The Pyramids of Giza consist of the Great Pyramid of Giza (also known as the Pyramid of Cheops or Khufu and constructed c. 2560 -- 2540 BC), the somewhat smaller Pyramid of Khafre (or Chephren) a few hundred meters to the south - west, and the relatively modest - sized Pyramid of Menkaure (or Mykerinos) a few hundred meters farther south - west. The Great Sphinx lies on the east side of the complex. Current consensus among Egyptologists is that the head of the Great Sphinx is that of Khafre. Along with these major monuments are a number of smaller satellite edifices, known as ``queens ''pyramids, causeways and valley pyramids.

paragraph_text: The market square lies on the street running south from the palace to Ettlingen. The market square has the town hall ("Rathaus") to the west, the main Lutheran church ("Evangelische Stadtkirche") to the east, and the tomb of Margrave Charles III William in a pyramid in the buildings, resulting in Karlsruhe being one of only three large cities in Germany where buildings are laid out in the neoclassical style.

paragraph_text: Ground was broken for the Luxor in March 1992 and the resort officially opened at 4 AM on October 13, 1993, to a crowd of 10,000 people. When it opened, the pyramid, which cost $375 million to build, was the tallest building on the strip and contained 2,526 rooms and a 100,000 sq ft (9,300 m) casino. The resort was financed by ``petty cash ''earned from other Circus Circus Enterprises properties and did not include any outside financial investors. The hotel's pyramid is similar in size to the Red Pyramid and Bent Pyramid of Egypt.

paragraph_text: The Transamerica Pyramid at 600 Montgomery Street between Clay and Washington Streets in the Financial District of San Francisco, California, United States, is a 48 - story postmodern building and the second - tallest skyscraper in the San Francisco skyline. Its height will be surpassed by Salesforce Tower, currently under construction. The building no longer houses the headquarters of the Transamerica Corporation, which moved its U.S. headquarters to Baltimore, Maryland, but it is still associated with the company and is depicted in the company's logo. Designed by architect William Pereira and built by Hathaway Dinwiddie Construction Company, at 853 feet (260 m), on completion in 1972 it was the eighth - tallest building in the world.

paragraph_text: Charpentier Pyramid () is a pyramid-shaped peak rising to in the northwest part of the Herbert Mountains, Shackleton Range. In association with the names of glacial geologists grouped in this area, it was named by the UK Antarctic Place-Names Committee in 1971 after Jean de Charpentier, a Swiss engineer and mineralogist who in 1835 gave additional proof on the former extension of glaciers.

paragraph_text: Userkaf's pyramid is located on the northeast corner of Djoser's step pyramid complex. The pyramid was originally around 49 metres (161 ft) high and 73 metres (240 ft) large with an inclination of 53° identical to that of Khufu's great pyramid for a total volume of 87,906 m3 (114,977 cu yd). The core of the pyramid is built of small, roughly-hewn blocks of local limestone disposed in horizontal layers. This meant a considerable saving of labor as compared to the large and more accurately-hewn stone cores of 4th Dynasty pyramids. However, as the outer casing of Userkaf's pyramid fell victim to stone robbers throughout the millennia, the loosely assembled core material was progressively exposed and fared much worse over time than that of the older pyramids. This explains the current ruined state of the pyramid.The pyramid core was constructed in a step-like structure, a construction technique similar to that of the 4th dynasty although the building material was of a significantly lower quality. The outer casing of the pyramid was made of fine Tura limestone which certainly ensured Userkaf's construction an appearance similar to that of the glorious 4th Dynasty pyramids. There was however no red granite paneling over the lower part of the pyramid as in the case of the Pyramid of Menkaure.
