# How many balls, each of radius 1 cm, can be made from a solid sphere of lead of radius 8 cm?

Answer :

Sum of volumes of balls that can be made from a large sphere will have same volume, as that of the sphere.

As we know that, volume of a sphere = . Given that, radius of large sphere, r_{1} is 8 cm and that of the small spheres, r_{2} is 1 cm.

Therefore, number of small balls that can be made from the big sphere =
