Fig 1. Net of a dodecahedron.
In the case of rhombic dodecahedra, the twelve faces are twelve rhombuses, and in the case of pentagon dodecahedra (pentadodecahedra) twelve regular pentagons.
|Fig 2. A cube inside a dodecahedron.|
If the edges of pentadodecahedron are extended, a new solid arises called the dodecahedron-star (see Figure 3).
