Given that a solid sphere of radius =8 cm
With this sphere, we have to make spherical balls = 1 cm
Since we don’t know number of balls let us assume that number of balls be n
We know that,
Volume of the sphere = 43∏r3
The volume of the solid sphere equal to sum of the n spherical balls.
= n(43∏13)= 43∏r3
= n= 8³ =n= 512
Hence 512 numbers of balls can be made of radius 1 cm of a solid sphere of radius 7.5cm.

answer:−
it's Given that solid sphere radius is =8 cm
With this sphere, we have to make spherical balls = 1 cm
Since we don’t know no. of balls let us assume that number of balls be n
Volume of the sphere = 4/3∏r3
The volume of the solid sphere equal to sum of the n spherical balls.
= n(4/3∏13)= 4/3∏r3
= n= 8³ =n= 512
Hence 512 numbers of balls can be made of radius 1 cm of a solid sphere of radius 7.5cm.
