Polyhedra may be classified and are often named according to the number of faces. The naming system is based on Classical Greek, and combines a prefix counting the faces with the suffix "hedron", meaning "base" or "seat" and referring to the faces.

Let's analyze this three-dimensional shape. One thing is clear and that is it is a polyhedron. The second thing you see is its faces. The faces resemble the triangles but the base is different. The base looks like a hexagon and the hexagon is a polygon. However, we want you to note one thing and that is the base can change.
