Question

A cube of metal of side 40 cm is melted down and
formed into 6000 balls of bearing. Determine the
radius of each ball.​

Answer 1

Answer:

Volume of cube= 40³=64000cm³

No. of balls made=6000

Volume of 1 ball = vol of cube / no.of balls made

                          = 64000/6000=10.66 cm³

Volume of 1 ball=4/3πr³

10.66=4/3 x 22/7 x r³

10.66 x 3/4 x 7/22= r³

r³=2.5437

∛2.5437=r

r = 1.365 cm
