A cylinder has 2 flat, parallel faces.
Yes.
All the faces of a triangular prism must be flat. So finding them should not be too difficult!
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.
A prism has no curved surfaces. It has 5 or more flat faces.
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.
A cylinder has 2 opposite parallel flat faces
A flat square has 4 faces.

There are five of them.
