Inscribing a Sphere Inside a Cube

When a sphere is inscribed snugly within a cube of side length s, the diameter of the sphere is d = s, meaning radius r = s / 2.

Cube Volume = s³
Cube Surface Area = 6s²
Geometry Formula

Cube Volume Formula

V = a³

Where V is the volume and a is the edge length of the cube.
