HOW TO BUILD A PYRAMID!?
How the Ancient Egyptians built the pyramids is still hotly debated; no
building plans or construction methods have survived. Pyramid
foundations appear to have been extremely precise (the base of Khufu’s
pyramid is level to 2cm) but several theories exist as to how the blocks
of stone were actually laid. Ramps are thought by some to have been
used, while others believe some sort of lever system may have been set
up. Some Egyptologists estimate that 300 stones a day were laid during
the building of a pyramid.
