Figure 1: Regular dodecahedron

A dodecahedron is a twelve faced polyhedron.[2] A regular dodecahedron has twelve faces, each of which is a regular pentagon. A regular dodecahedron has 60 vertices. In nature, a dodecahedron is found in the carbon molecule buckminsterfullerine. A carbon atom is at each vertex of a dodecahedron in a molecule of buckminsterfullerine.
