Volume of cube=4×4×4=64
as the sphere touches the side of the cube
dia=4
radius=2
volume f sphere=4/3Лr²=33.51cm³
hence volume of the gap=v of cube-v of sphere
64-33.51=30.49cm³

Volume of cube = (side)³( =(4)³ = 64 cm³
as the sphere is touching sides of cube, so the diameter of sphere is equals to the side of the cube, i.e. diameter is 4 cm
Hence, radius = 2 cm
volume of sphere = (4/3)πr³ = (4/3)π×(2)³ = 704/21 ≈ 33.52 cm³
volume of the gap between them = 64 - 33.52 =30.48 cm³
