Why are the pyramids so big?
assistant
The pyramids were built as tombs for the pharaohs. The pharaohs were buried in the pyramids, and the pyramids were built to hold the pharaoh’s body. The pyramids were also built to protect the pharaoh’s body from the elements. The pyramids were made of limestone, which is a very hard stone. The limestone was quarried from the Giza plateau, which is a very flat area. The limestone was then cut into blocks, and the blocks were then put together to form the pyramids.
