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?
Let the total number of bullets be `x`

Explanation

Let the total number of bullets be `x`
Radius of a spherical bullet`=4/2 cm=2cm`
Volume of a spherical bullet `=4/3xxpixx(2)^3=4/3xx22/7xx8cm^3`
Volume of x spherical bullets`=4/3xx22/7xx8xx(x)cm^3`
Volume of solid cube `= (44)^3cm^3`
Clearly, volume of x spherical bullets = Volume of cube
`=4/3xx22/7xx8x=44^3`
`x=(44xx44xx44xx3xx7)/(4xx22xx8)=2541`
Total number of bullets`=2541`
