Dodecahedron and its Side Length

Area

Unit
Area of a dodecahedron. It consists of twelve pentagonal planes. The prefactor is approximately:$$ 3 \sqrt{25 ~+~ 10 \, \sqrt{5}} \approx 20.646 $$

Side length

Unit
Side length of a dodecahedron. Since it is a regular polyhedron, all sides have the same length.
