Product of Number of Edges, Edges per Face and Faces of Regular Dodecahedron

Theorem
The product of the number of edges, edges per face and faces of a regular dodecahedron is $1800$.

Proof
A regular dodecahedron has:
 * $30$ edges

and:
 * $12$ faces.

Each face is a pentagon, and so has $5$ edges.

Hence:
 * $30 \times 12 \times 5 = 1800$
