Question

the number of spherical balls can be made out of a solid cube of lead who was his measures 22 centimetres and he's got bring being 2 centimetres in diameter is

Answer 1

let N no of balls form by cube
volume of cubic lead=(22)^3
volume of spherical ball=4/3pi (1)^3
N=volume of cubic lead/volume of spherical ball
=22x22x22/(4/3x22/7x1)
=2541
hence 2541 ball form easily by lead cube
