The great pyramids of Giza are among the most famous landmarks in the world, but they are still shrouded in mystery. There are three pyramids at Giza, and these are known as Khufu, Khafre and Menkaure. One of the most fundamental controversies surrounding the pyramids is how they were built given the weight of a single block.

The great pyramid of Khufu, which is also known as Akhet Khufu, consists of an estimated 2.3 million blocks of stone. Each stone block within the pyramid weighs approximately 2267.96 kilograms (2.5 tons). Therefore the total weight of the great pyramid of Khufu is approximately:

2,300,000 x 2267.96 = 5,216,308,000 kilograms (5,750,000 tons).
