How many balls, each of radius , can be made from a solid sphere of lead of radius ?

It is given in the question that,

A solid sphere of radius,

With this sphere, we have to make spherical balls of radius

Now, assume that the number of balls made as n

As, we know that

Formula for volume of the sphere

The volume of the solid sphere sum of the volumes of n spherical balls.

Hence, 512 balls can be made of radius each with a solid sphere of radius .
