Tetrahedron Calculator

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

Euclid Edge length (a): Tetrahedron
4 faces, 6 edges, 4 vertices
Faces: equilateral triangles
Height (h):
Surface area (A):
Volume (V):
Exsphere radius (re):
Midsphere radius (rm):
Insphere radius (ri):
Round to    decimal places.



Formulas:
h = a / 3 * √6
A = a² * √3
V = a³ / 12 *√2
re = a / 4 * √6
rm = a / 4 * √2
ri = 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).
