Let a be the side of cube. Volume of cube = a³     .........................(1)

if a sphere is inscribed in a cube of radius a, then its radius is a/2.
Volume of the sphere = (4/3)π(a/2)³ = (1/6)πa³    ............................(2)

volume of cube : Volume of sphere = a³ : (1/6)πa³   = 6:π = 6 : (22/7)
