Definition:Dodecahedron

Definition
A dodecahedron is a polyhedron which has $12$ faces.

Linguistic Note
The word dodecahedron derives from the Classical Greek δωδεκάεδρόν:


 * dodeca (δωδεκά), meaning twelve
 * hedron (a form of ἕδρα), meaning base or seat.

The technically correct plural of dodecahedron is dodecahedra, but the word dodecahedrons can often be found.
