Answer:The no of ball are 512
Step-by-step explanation:
Radius of sphere = 8cm.
Vol of sphere = 4/3*pi*r*r*r.
Radius of ball = 1cm.
Vol of ball = 4/3*pi*r*r*r.
Let no of balls = n.
Vol of sphere = n*(Vol of ball)
4/3*pi*r*r*r = n*4/3*pi*r*r*r
8*8*8 = n*1*1*1
n = 512.
Therefore no of balls are 512.

No of balls=
Volume of SPHERE / Volumeof sphere
4/3 pi (r1)3 / 4/3 pi (r2)3
[4/3 pi gets cancelled]
(r1)3 / (r2)3
r1 × r1 × r1 / r2 × r2 × r2
8×8×8 / 1×1×1
512 balls
