Class 9th RD Sharma - Mathematics 21. Surface Area and Volume of a Sphere

Answer :

Volume of a cube = side³

Volume of a sphere = (4/3)πr³

Given, cube of side 4 cm contains a sphere touching its side

Radius of the sphere = 4/2 = 2 cm

Volume of the gap in between = 4³ - (4/3)π × 2³

⇒ Volume of the gap in between = 30.48 cm³
