Question
A solid spherical gold ball
having a radius of 10 cm is melted to form smaller balls of radius 5 mm each. Find the number of such spherical gold balls obtained.Solution
ATQ,
The volume of the larger ball will be equal to the combined volume of all the smaller balls. Let the number of smaller obtained be ‘n’. Therefore, 
Simplifying, 
Thus, the number of smaller balls obtained is 8000 .
