A hexagonal prism has eight faces, six of which are rectangles, and two of which are hexagons. A hexagonal prism consists of a top and bottom hexagon that are both joined by straight lines connecting each set of vertices.
Prisms are the simplest way to turn a two dimensional polygon into a three-dimensional shape. A simple prism consists of two identical shapes on either end, connected with straight lines at each set of vertices. The shapes are named for the shapes on the end. For example, triangular prism and square prisms are the two simplest types of prisms. The amount of faces will always be equal to two plus the amount of edges of the base shape.
