Faces
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.
A rectangular prism has 6 flat surfaces
It has 6 faces which are its flat surfaces.
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.
