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.

Example truncated triangular prism. Its top face is truncated at an oblique angle, but it is not an oblique prism.
