A solid metallic sphere of radius 8 cm is melted and into spherical balls each of radius 2 cm. Find the number of spherical balls obtained.

Given,


Radius (R) of the solid metallic sphere = 8 cm


Radius (r) of the spherical ball = 2 cm


Now,


The number of spherical balls obtained =



= (R/r)3


= (8/2)3


= 43


= 64


So,


The number of spherical balls obtained is 64.
