Spherical ball=r=0.1cm
Sphere=r=1cm
Therefore,
No. of balls= 1*1*1÷0.1*0.1*0.1
= 1*1*1*10*10*10÷1*1*1
= 10*10*10
= 1000
Thus, we have total 1000 balls from the merely sphere.

it will not work in all question s
why
then how
when values are not like 1 & 0.1
we can divide their volume and can get answer
I have mentioned the answer 1000 balls by doing division only.
i say it will not work in all questions but in few it work. by dividing volume
