A pyramid is a geometric shape formed by connecting a polygonal base and a point called the apex, by triangular faces. When unspecified the base is usually assumed to be square. One of the platonic solids, the tetrahedron, is a triangular pyramid. The square and pentagonal pyramids can also be constructed with all faces regular, and so count among the Johnson solids. All pyramids
formula
Area of the base * Height * 1/3
