# Tetrahedron Calculator

Make calculations in a regular tetrahedron. Enter one value and, when needed,
change the number of decimal places. Then click Calculate.

**Formulas:**

h = a / 3 * √6

A = a² * √3

V = a³ / 12 *√2

r_{e} = a / 4 * √6

r_{m} = a / 4 * √2

r_{i} = a / 12 * √6

Edge length, height and radius have the same unit (e.g. meter), the area has this unit squared (e.g. square meter), the volume has this unit to the power of three (e.g. cubic meter).
