About this calculation
The inradius of a tetrahedron, which is the radius of the largest sphere that can fit inside the tetrahedron, is half the length of the tetrahedron's edge.
Formula
To calculate the tetrahedron inradius, you can use the following formula.
Inradius = \( \frac{ s \sqrt{6} }{12} \)
