Inscribed Sphere Volume



A cube with a side length (S) of 5 has an inscribed sphere with a volume (V) of 65.4498.

Inscribed Sphere Volume Formula

the Volume of a sphere with radius (R) can be found with this formula

  • V = (4/3)πR3

the radius (R) of a sphere inscribed in a cube with side length S can be found with this formula

  • R = S/2

by combining the two formulae we can determine the Volume of an inscribed sphere in terms of cube Side length

  • V = (4/3)π(S/2)3
Volume of a Sphere Inscribed in a Cube Formula

Given a cube with a side length S the volume (V) of an inscribed sphere can be found by substituting the formula for finding the Radius of an inscribed sphere into the formula for finding the Volume of a sphere.

Cube
A cube is a three dimensional geometry with six equal square faces meeting at ninety degrees along each edge and aligned with each vertex being formed from the intersection of three squares so that a completely enclosed volume is formed
Rectangular Prism
A rectangular prism is a three dimensional geometry with six faces. Unlike a cube the edge legths of each face may be unequal but parallel. Like a cube all faces must meet along the edges and align to form a vertex from the intersection of three faces so that the prism has a completely enclosed volume.
