Close-up of the Great Pyramid of Giza

The volume of the Great Pyramid of Giza is 2,583,283 cubic meters. To build Giza’s great pyramid, the ancient builders used around 2.3 million stones weighing, on average, 3 tons. The Great Pyramid of Giza was the most accurately aligned structure on the planet’s surface, facing true north with only 3/60th of a degree of error.

The four faces of the Great Pyramid are slightly concave, making it the only pyramid built this way. Despite what you may think about this ancient structure, the Great Pyramid of Khufu is an eight-sided figure, not a four-sided figure. Each of the pyramid’s four side are evenly split from base to tip by very subtle concave indentations.
