Question

How many spherical lead shots of diameter 4 cm can be made out of a solid cube of lead whose edge measures 44 cm.

Answer 1

Volume of cube = a³ where, a = side of cube

For cubical lead ;

side, a = 44 cm

Volume of lead = 44(44)(44) cm³

For spherical shots,

Diameter = 4 cm

Radius, r = 2 cm

[As radius = diameter/2]

So, 2541 bullets can be made from lead.
