This is key, given the Great Pyramid’s 2.3 million blocks, each weighing a lot. The engineering used was ahead of its time. It shows the ancient Egyptians’ advanced knowledge. Geometry was key ...

At 146.5 m (481 ft) high, the Great Pyramid stood as the tallest structure in the world for more than 4,000 years. Today it stands at 137 m (449.5 ft) high, having lost 9.5 m (31 ft) from the top.

More than 2,300,000 limestone and granite blocks were pushed, pulled, and dragged into place on the Great Pyramid. The average weight of a block is about 2.3 metric tons (2.5 tons). How much is that?

The clips explore the advanced mathematics and geometry used to build the pyramids with the aid of Egyptian artefacts and how the religious beliefs of the ancient Egyptians influenced the position ...
