Tetrahedron Volume Calculator

About this calculator

A regular tetrahedron — a solid with four equilateral triangular faces, all edges equal in length — has a volume given by the formula V = edge³ / (6√2) and a total surface area of 4 times (√3/4) times edge², since each of its four faces is an identical equilateral triangle.

This shape and its formulas appear across geometry education, crystallography (where tetrahedral coordination describes the bonding arrangement in structures like diamond and methane), and 3D modeling and game development, where tetrahedra are the simplest possible volumetric building block used in mesh generation and finite-element analysis.

Enter the edge length of a regular tetrahedron and this calculator returns both its volume and its total surface area.
