#### Question

A cube of side 4 cm contains a sphere touching its side. Find the volume of the gap in between.

#### Solution

It is given that
Cube side = 4cm
Volume of cube =(4cm)^3= 64cm^3
Diameter of the sphere = Length of the side of the cube = 4cm
∴ Radius of sphere = 2cm
Volume of the sphere =4/3πr^3 =4/3xx22/7xx(2)^3=33.52cm^3

∴ Volume of gap = Volume of gap – Volume of sphere
=64cm^2-33.52cm^3=30.48cm^3

Is there an error in this question or solution?
