The dimensions of the pyramid were 280 royal cubits (146.7 m; 481.4 ft) high, a base length of 440 cubits (230.6 m; 756.4 ft), with a seked of 5+1/2 palms (a slope of 51°50'40").
The Great Pyramid was built by quarrying an estimated 2.3 million large blocks weighing 6 million tonnes in total. The majority of stones are not uniform in size or shape and are only roughly dressed.[6] The outside layers were bound together by mortar. Primarily local limestone from the Giza Plateau was used. Other blocks were imported by boat on the Nile: White limestone from Tura for the casing, and granite blocks from Aswan, weighing up to 80 tonnes, for the King's Chamber structure.[7]
There are three known chambers inside the Great Pyramid. The lowest was cut into the bedrock, upon which the pyramid was built, but remained unfinished. The so-called[8] Queen's Chamber and King's Chamber, that contains a granite sarcophagus, are above ground, within the pyramid structure. Khufu's vizier, Hemiunu (also called Hemon), is believed by some to be the architect of the Great Pyramid.[9] Many varying scientific and alternative hypotheses attempt to explain the exact construction techniques.
