  1. Let r be the radius of the sphere and a be the side of the cube.

    Surface area of sphere = 4r2

    Surface area of cube = 6a2

    Given sphere and cube has same surface area.

    4r2 = 6a2

    r2/a2 = 6/4

    ML Aggarwal Sol Class 10 Maths chapter 17-7

    Volume of the sphere, V= (4/3)r3

    Volume of the cube, V= a3

    ML Aggarwal Sol Class 10 Maths chapter 17-8

    Hence proved.
