The flat surfaces on a pyramid are called faces. A pyramid has one base and triangular faces that meet at a single point called the apex. On a cube or rectangular prism, the flat surfaces are called faces as well. But unlike a pyramid, a cube has six square faces, while a rectangular prism has two rectangular bases and four rectangular faces.
That is called a tetrahedron.
base
"faces"
The height of the triangular face of a pyramid is called the slant height.
Cause it is Otherwise the shape would not be called a pyramid!
