Volume of a Regular Tetrahedron

Volume of a Regular Tetrahedron
\[V = \frac{a^3}{6\sqrt{2}}\]

Variables

Vvolume (m³)
aedge length of the tetrahedron (m)

Description

What is this formula?

This formula calculates the volume of a regular tetrahedron using the length of one edge. A regular tetrahedron is a three-dimensional solid composed of four equilateral triangular faces.


When to use it

Use this formula when determining the volume of symmetric tetrahedral structures or geometric models.


Example

If a regular tetrahedron has an edge length of 6 m:


V = 6^3 / (6√2)

V = 216 / (6√2)

V ≈ 25.46 m³
