How many bullets can be made out of a cube of lead, whose edge measures 22 cm, each bullet being 2 cm in diameter?
Edge of the cube (r)=22cm∴Volume=a3=(22)3cm3=22×22×22=10648cm3
Diameter of a bullet = 2 cm
∴ Radius (r) =22=1cm
∴ Volume of 1 bullet =43πr3
Number of bullets=Total volumeVolume of one bullet=10648×2188=2541
