Let the radius of solid sphere be R = 6 cm and the radius of each ball be r = 1 cm
No. of balls can be made =
=> Volume of solid sphere ÷ Volume of one ball
=> 4/3 π R³ ÷ 4/3 π r³
=> R³ / r³
=> (R/r)³
=> (6/1)³
=> 216 balls
Hope this helps.....

Answer:
Step-by-step explanation:
Volume of solid sphere = 4/3πr^3
=4/3x22/7x8x8x8
Volume of a ball =4/3πr^3
=4/3x22/7x1x1x1
Number of balls =(4/3xπx8x8x8).
--------------------
(4/3xπx1x1x1)
=512.
