Volume of the spherical ball of radius 8 cm = 4/3π x 83c3

Also, volume of each smaller spherical ball of radius 1cm = 4/3π x 13cm3.

Let n be the number of smaller balls that can be made. Then, the volume of the larger ball is equal to the sum of all the volumes of n smaller balls.

Hence, 4/3π x n = 4/3π x 83

=> n = 83 = 512

Hence, the required number of balls = 512.
