Question: How were the Pyramids at Giza built?
Position‹3 of 4›: The Incline Theory

Builders may have used the steep gradient of the pyramid itself to haul blocks up the sides. In this model, the workers worked on the flat top of the pyramid and used a system of ropes to bring blocks to the top. This theory is popular with engineers.

The Incline Theory is the quickest method to build a pyramid
Most pyramid building theories are extremely complicated. Any system of ramps would be difficult to build safely and slow to use. By using the sides of the pyramids as a slope to move the blocks, Egyptian workers could have moved the stone slabs into place quickly and easily.
