because the the sides of a based form a face of a pyramid
This pyramid would have a perpendicular height of 3, a volume of 64 units3 and a slant edge of 6.403
The base of a pyramid only has four sides, as it is a square. That is so not true. A tetrahedron is a pyramid with a triangular base. A pyramid can have any polygon as its base.
There are about three types of pyramids in Ancient Egypt: "True" pyramid- The typical pyramid, with smooth sides and hard edges(the pyramids you would imagine) Bent pyramid- Very smooth and has curved sides(obviously looks bent!) Stepped Pyramid- Has many steps to the top(it's a STEP pyramid!)
The first classic "smooth sided" pyramid shape was attempted by the Pharaoh Sneferu, who founded the 4th Dynasty of the Old Kingdom. Sneferu reigned from either 24-48 years, around 2600BCE, and during this time he was responsible for three separate pyramids. His first pyramid, the Medium Pyramid seems to be the first attempt at the classic pyramid. The Medium Pyramid is famous because it appears to have collapsed and was never finished. Sneferu's second attempt was the Bent Pyramid, which gets it name from the sharp angle its sides take about halfway up the sides. The third pyramid that Sneferu attempted is the Red Pyramid and is the first classical pyramid and was the tallest manmade structure in the world until Khufu's Great Pyramid at Giza was constructed.
