How many spherical bullets can be made out of a solid cube of lead whose edge measures 44 cm, each bullet being 4 cm in diameter?

Explanation

volume of cube = `(44)^3`

volume of bullet = `4/3 pi (2)^3`

Volume of 1 bullet `xx`n = volume of cube

`4/3 pi xx (2)^3 xx n = (44)^3`

`n = (444/2)^3 xx 3/4 xx 7/22`

`= 22 xx 22 xx 22 xx 3/4 xx 7/22`

`n = 121 xx 21`

`n = 2541`
