# Regular Octahedron Volume

## Description

An octahedron is a polyhedron with eight faces. A regular octahedron is a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.

A regular octahedron is the dual polyhedron of a cube. It is a rectified tetrahedron. It is a square bipyramid in any of three orthogonal orientations. It is also a triangular antiprism in any of four orientations.The volume of the regular octahedron can be computed by the length of the edge.

## Variables

V_{oc} | Volume of the regular octahedron (m^{3}) |

a | Length of the edge of the octahedron (m) |
