A dodecahedron is a type of polyhedron that is classified as one of the five Platonic solids. Specifically, it is a three-dimensional shape with the following properties:
1. Each face of a dodecahedron is a regular pentagon.
2. Every vertex of a dodecahedron is shared by three faces.
To determine the number of faces on a dodecahedron, we rely on the definition and properties of this geometric shape. A dodecahedron has:
- 12 faces.
Therefore, the correct answer is:
C. 12
