Cube A of side x
Sphere B of radius x
Find ratio of volume of A:B
Volume of the cube is side cubed = x³
Volume of the sphere = 4/3πr³ = 4/3 ×22/7 × x³ = 88/21x³
Find the ratio of x³ : 88/21x³
divide each side by x³ = 1:88/21
multiply each side of the ratio by 21 = 21:88
Therefore the ratio of the volume of A:B is 21:88
= 21:88
