# Rhombic triacontahedron Volume

## Description

Rhombic triacontahedron is a convex polyhedron with 30 rhombic faces. It has 60 edges and 32 vertices of two types. The ratio of the long diagonal to the short diagonal of each face is exactly equal to the golden ratio.

The volume of a triacontahedron is related to its edge length.

## Variables

V | Rhombic triacontahedron Volume (m^{3}) |
