Explanation:

The Great Pyramid of Giza is a defining symbol of Egypt and the last of the ancient Seven Wonders of the World. It is located on the Giza plateau near the modern city of Cairo and was built over a twenty-year period during the reign of the king Khufu (2589-2566 BCE, also known as Cheops) of the 4th Dynasty. Until the Eiffel Tower was completed in Paris, France in 1889 CE, the Great Pyramid was the tallest structure made by human hands in the world; a record it held for over 3,000 years and one unlikely to be broken. Other scholars have pointed to the Lincoln Cathedral spire in England, built in 1300 CE, as the structure which finally surpassed the Great Pyramid in height but, still, the Egyptian monument held the title for an impressive span of time. The pyramid rises to a height of 479 feet (146 metres) with a base of 754 feet (230 metres) and is comprised of over two million blocks of stone. Some of these stones are of such immense size and weight (such as the granite slabs in the King's Chamber) that the logistics of raising and positioning them so precisely seems an impossibility by modern standards.

The pyramid was first excavated using modern techniques and scientific analysis in 1880 CE by Sir William Matthew Flinders Petrie (1853-1942 CE), the British archaeologist who set the standard for archaeological operations in Egypt generally and at Giza specifically. Writing on the pyramid in 1883 CE, Flinders Petrie noted:
