## Inscribed Sphere Radius

A cube with a side length (S) of 4 has an inscribed sphere with a radius (R) of 2.

## Inscribed Sphere Radius Formula

for cubes with a side length S find the radius R of the inscribed sphere

- R = S/2

substitute the side length S with the measured value, in this example lets use a side length of 4

- R = 4/2

divide the side length in half to find the radius of an inscribed sphere

**R = 2**

Given a cube with a side length S the radius (R) of an inscribed sphere can be found by dividing the cube side length in half.
