The formula to calculate the Insphere Radius of Tetrahedron is:
\[ ri = \frac{le}{2 \cdot \sqrt{6}} \]
Insphere Radius of Tetrahedron is the radius of the sphere that is contained by the Tetrahedron in such a way that all the faces just touch the sphere. Edge Length of Tetrahedron is the length of any of the edges of the Tetrahedron or the distance between any pair of adjacent vertices of the Tetrahedron.
Let's assume the following values:
Using the formula:
\[ ri = \frac{10}{2 \cdot \sqrt{6}} = 2.04124145231932 \]
The Insphere Radius is 2.04124145231932 Meters.
