Question

A solid ball is exactly fitted inside a cubical box. find the the side of cube if volume of sphere is 4/3πa³
​

Answer 1

Answer:

if the ball is fitted inside the cubicak box, then diameter of the bank mist be equal to the distance between opposite face of the cube which is =a

therefore R=2a

so, the volume of sphere (ball)

3by 4π[2a]3= 6

πa=3
