**Calculate the Volume of a Tetrahedron**

A tetrahedron is a polyhedron composed of 4 triangular faces, where 3 of which meet at each vertex. For the purposes of our volume calculation, we'll be using a regular tetrahedron. A regular tetrahedron is one where the 4 triangles are equilateral. The volume of a regular tetrahedron is calculated by using the length of one of it's edges.

**Method #2 – Volume of a Tetrahedron Formula**

The volume of a tetrahedron can be calculated by using the formula:

In this formula, “a” is cubed and represents the length of the tetrahedron’s edge.
