Question

The Great Pyramid of Giza was constructed as a regular pyramid with a square base. It was built with an approximate volume of 2592276 cubic meters and a height of 146.5 meters. What was the length of one side of its base, to the nearest meter?

Answer 1

volume of a square-based pyramid = base edge^2 * height/3
so:
2,592,276 = base edge^2 * 146.5/3; therefore the base edge is approximately 230.4m
