How Long Did It Take?

The Great Pyramid was built by Slaves over a period of twenty years by the Pharoah

It is believed the pyramid was built as a tomb for Fourth Dynasty Egyptian pharaoh Khufu (often Hellenicised as “Cheops”) and was constructed over a 20-year period. Khufu’s vizier, Hemon, or Hemiunu, is believed by some to be the architect of the Great Pyramid.

Based on a mark in an interior chamber naming the work gang and a reference to fourth dynasty Egyptian Pharaoh Khufu,[1][2] 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. Other Ideas

Good story thus far… How many stone blocks were used to build this structure = Egyptians try to say that 2.3 million stone blocks, 2.5 to 15 tons each. How many hours are in 20 years? 24 hours in a day, 7,300 days in 20 years. Using Unit Converter, 7,300 days x 24 hours = 175,200 hours. That would mean that 13.1278539 stones had to be moved into place each hour, 24 hours each day for the full twenty years.

A modern construction management study, in association with Mark Lehner and other Egyptologists, estimated that the total project required an average workforce of 14,567 people and a peak workforce of 40,000. Without the use of pulleys, wheels, or iron tools, they used critical path analysis to suggest that the Great Pyramid was completed from start to finish in approximately 10 years
