Step-by-step explanation:
Let the radius of the spherical steel ball be 'X'
Then the volume of the spherical steel ball=4/3πr³=4/3π(X)³
Let the radius of the small spherical balls be 'x'
Then, Volume=4/3π(x)³
According to question:-
4/3π(X)³=8[4/3πx³]
4/3(X)³=32/3x³
(X)³=8x³
X=2x
Therefore ratio- 1:2
