The pyramids of Egypt were built as tombs. Most people who were buried in them were Egyptian pharaohs, or kings.
The Great Pyramid, or the Pyramid of Khufu (Cheops), is believed to be about 4,500 years old. It sits on the Giza Plateau, which borders Cairo, Egypt.
The pyramids are made of different materials, but most are limestone, sandstone or other stone. The average stone block used to build the Great Pyramid weighs 2.75 tons.
No wheels or cranes existed when the pyramids of Egypt were built. Many scientists believe that the Egyptians used ramps to pull the stones to their desired height.
Egyptologists estimate that more 10,000 men worked on each pyramid at some point during its construction.
