Question: How many square miles is the continent on which Mount Tchaikovsky can be found?

full_context: Document 1: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
Document 2: Mount Kibal'chich: Mount Kibal'chich () is the highest peak, high, of the Kvaevenutane Peaks, in the Payer Mountains of Queen Maud Land, Antarctica. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, and was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60. It was remapped by the Soviet Antarctic Expedition, 1960–61, and named after the Russian revolutionary Nikolai Kibalchich.
Document 3: Mount Liszt: Mount Liszt is a snow-covered mountain, about high, with a scarp on its southeastern face, rising northeast of Mount Grieg, on the Beethoven Peninsula, situated in the southwest portion of Alexander Island, Antarctica. A number of mountains in this vicinity first appear on maps by the Ronne Antarctic Research Expedition (RARE), 1947–48. This mountain, apparently one of these, was mapped from RARE air photos by D. Searle of the Falkland Islands Dependencies Survey in 1960, and was named by the UK Antarctic Place-Names Committee after Franz Liszt, the Hungarian composer.

Document 5: Antarctic Plate: The Antarctic Plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau and extending outward under the surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea), the Antarctic plate began moving the continent of Antarctica south to its present isolated location causing the continent to develop a much colder climate. The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems. The adjoining plates are the Nazca Plate, the South American Plate, the African Plate, the Somali Plate, the Indo-Australian Plate, the Pacific Plate, and, across a transform boundary, the Scotia Plate.
Document 6: Gluck Peak: Gluck Peak () is a rock peak, high, located south-southwest of Mount Borodin and immediately north of Alyabiev Glacier, lying between the bases of Bennett Dome and Shostakovich Peninsula on south side of the Beethoven Peninsula, southwest Alexander Island, Antarctica. It was first mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and was named by the UK Antarctic Place-Names Committee after Christoph Willibald von Gluck, the Austrian composer (1714-1787).
Document 7: Antarctica: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Document 8: Mount Kropotkin: Mount Kropotkin is a peak on the west side of Jøkulkyrkja Mountain in the Mühlig-Hofmann Mountains of Queen Maud Land, Antarctica. It was mapped by the Norsk Polarinstitutt from surveys and air photos by the Sixth Norwegian Antarctic Expedition, 1956–60. The peak was also mapped by the Soviet Antarctic Expedition in 1961 and named for Russian anarchist Peter Kropotkin.
Document 9: Antarctica: Antarctica (US English i/æntˈɑːrktɪkə/, UK English /ænˈtɑːktɪkə/ or /ænˈtɑːtɪkə/ or /ænˈɑːtɪkə/)[Note 1] is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
Document 10: Antarctica: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.
Document 11: Vivaldi Glacier: Vivaldi Glacier () is a glacier lying between the Colbert Mountains and the Lully Foothills, flowing south from Purcell Snowfield into the head of Schubert Inlet on the west coast of Alexander Island, Antarctica. The feature appears to be first shown on maps of the United States Antarctic Service (USAS) which photographed Alexander Island from the air in 1940. It was mapped from air photos obtained by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. Named "Vivaldi Gap" by the United Kingdom Antarctic Place-Names Committee in 1961, after Antonio Vivaldi (1678–1741), Venetian composer. The name was amended to Vivaldi Glacier following review of Landsat program imagery, 1979, displaying flow lines in the feature.
Document 12: Stravinsky Inlet: Stravinsky Inlet () is an ice-covered inlet lying between Shostakovich Peninsula and Monteverdi Peninsula in southern Alexander Island, Antarctica. The inlet was first mapped by Directorate of Overseas Surveys from satellite imagery supplied by U.S. National Aeronautics and Space Administration in cooperation with U.S. Geological Survey. Named by United Kingdom Antarctic Place-Names Committee after Igor Stravinsky (1882–1971), Russian-born composer who became a French citizen, ultimately a citizen of the United States.
Document 13: Antarctica: Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Document 14: Vittoria Buttress: Vittoria Buttress () is a conspicuous rock cliff, rising to about 750 m, overlooking the southeast side of Lazarev Bay and forming the northwest extremity of the Lassus Mountains in northern Alexander Island, Antarctica. The feature was first mapped from air photographs taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. Named by the United Kingdom Antarctic Place-Names Committee for Tomas Luis de Victoria (1535–1611), Spanish composer.
Document 15: Mount Tchaikovsky: Mount Tchaikovsky () is a snow-covered mountain, rising to about 600 m, with scarps on the south and east sides, located in the north part of Derocher Peninsula, situated in the southwest portion of Alexander Island, Antarctica. A number of mountains in this vicinity first appear on maps by the Ronne Antarctic Research Expedition in 1947-48. This mountain, apparently one of these, was mapped from RARE air photos by Searle of the Falkland Islands Dependencies Survey in 1960. The feature was named by United Kingdom Antarctic Place-Names Committee after Peter Ilyitch Tchaikovsky (1840–93), Russian composer.
