Clay balls

How many clay balls with a radius of 1 cm can be made from a ball of clay with a radius of 8 cm?

Correct answer:

n =  512

Step-by-step explanation:

R=8 cm r=1 cm  V1=43 π R3=43 3.1416 832144.6606 cm3 V2=43 π r3=43 3.1416 134.1888 cm3  n=[V1/V2]=[2144.6606/4.1888]=512   Verifying Solution:  n1=R3/r3=83/13=512
