Question

How mañy bullets can be made out of a cube of lead, whose edge measures 22 cm, each bullet being 2 cm in diameter?

Solution

Cube edge= 22cm

∴ Volume of cube=(22)^3

=10648cm^3

And,
Volume of each bullet =4/3πr^3

=4/3×22/7×(2/2)^3

=4/3×22/7

=88/21cm^3

∴No. of bullets="Volume of cube"/"Volume of bullet"

=10648/(88/21)=2541
