geometric shape, a polyhedron with an n-sided polygonal base From Wikipedia, the free encyclopedia
A prism is a three-dimensional shape, which is made of two polygons at each of its two ends. Each pair of polygon sides on the same axis will have a quadrilateral (four-sided shape) face between them.

There are an infinite number of different prisms, which can be based on a polygon with any number of sides.
A cube is a special kind of prism with squares for the faces on its ends and for the faces between them.
