Radius of Sphere Inscribed in Cube Calculator

Calculate the Inscribed Sphere's Radius

Units
Enter the numerical value for the cube's side length.

Effortlessly determine the radius of a sphere perfectly inscribed within a cube. This online calculator simplifies complex geometry by applying the direct formula: radius = side length / 2. Ideal for quick checks and learning.

Formula:

To calculate the radius (r) of a sphere inscribed in a cube, simply divide the cube's side length (s) by 2. The diameter of the inscribed sphere is equal to the side length of the cube.

Formula: r = s / 2
