The tomb of the fourth dynasty Pharaoh Khufu is the largest pyramid. It was built around 2700 BC. If the building stone is loaded by a truck with a load of 7 tons, it needs 9.78 million. If these trucks are one after another, the total length is 6200 kilometers.
The Havla Pyramid is the second largest pyramid, and a huge Sphinx stands beside it. It is said that in 26 10 BC, when Hafra, the third Pharaoh of the fourth dynasty in Egypt, visited his soon-to-be-completed mausoleum, he found an abandoned boulder in the quarry, so he ordered the stonemason to carve a stone statue according to his face.
1798, when Napoleon occupied Egypt, he ordered heavy artillery to bombard the Sphinx, only a few beards were broken. Napoleon once estimated that if the stones of the three adjacent pyramids of Khufu, Havla and Menkaufra were gathered together, a stone wall with a height of 3 meters and a thickness of 1 m could be built to enclose the whole of France.
But where did so many stones come from? According to textual research, ordinary stones may be taken from nearby materials. The white limestone used for the outer layer was taken from the Mukatam quarry on the east bank of the Nile. The granite in the inner tomb was taken from Aswan, more than 800 kilometers away. Quarrying, transporting, going down the river and landing require not only a large number of transport manpower, but also a group of engineers, builders and managers of considerable scale, plus an army with sufficient suppression ability. In addition, they must have food, clothes and shelter, as well as a huge service staff. It is estimated that 50 million people are needed to support such a huge construction project, and it is generally believed that the total population of the world will not exceed 20 million around 3000 BC. In addition, as many as 80 pyramids have been discovered. Even if Herodotus said in History, it will take 2400 years to complete one in 30 years. Can Egypt afford such long-term consumption?
