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

I think you can make 8 balls from the solid sphere

512

Step-by-step explanation:

Volum of sphere:4*pi*r³/3.

Now, the volum of the original sphere is: Vo=4*pi*8³/3.

The volumn of a small ball is:

Vs=4*pi*1³/3

But the numbers of small balls is:

Vo=n*Vs

After simplification we have:

8³=n*1³=n

So n=8³=512, so 512 small balls can be made from original sphere.
