Cube Inradius Calculator

The Cube Inradius calculator calculates the radius of the incircle of a cube by taking the length of its side as input.

How to use Cube Inradius Calculator

Enter ✎ value for length of side \((s)\).
The result appears beneath the inputs as you enter values.

About this calculation

The inradius of a cube, which is the radius of the largest sphere that can fit inside the cube, is half the length of the cube's edge.

Formula

To calculate the cube inradius, you can use the following formula.

Inradius = \( \frac{ s }{2} \)
