Step-by-step explanation:
let the side of cube = 2a
therefore diameter of sphere =2a
that means radius of sphere = a
volume of cube = (side)*3
volume of sphere = 4 π r*3
3
ratio of volume of cube to the volume of sphere
= (side )*3
4 π r*3
3
= ( 2a )*3 [ side of cube = 2a ]
4 π (a)*3 [ radius of sphere = a ]
3
= 8a*3 × 3
4 × π × a*3
= 2 × 3
π
= 6
π
therefore ratio = 6 : π
( option b )
