Answer:63
Step-by-step explanation:
volume of a sphere is 0.5236 x d x d x d where d is diameter
in the case of ball with 12cm radius i d is 24
its volume is 0.5236x24x24x24 = 7238.2464
in the case of ball with diameter 6 cm is
0.5236x6x6x6 =113.0976
7238.2464 /113.0979 = 63.9998
ther for 63 sphere can be make
