- from Pyramids
Building a pyramid was difficult and dangerous. It required a highly organized society.
Thousands of skilled and unskilled workers were needed. To complete the Great Pyramid at Giza, one huge stone block must have been quarried, shaped, and smoothed every two minutes for 23 years!
No one has ever found plans for how to build a pyramid. But experts have made some good guesses, based on what we know of modern construction.
