How many spherical bullets can be made out of a solid cube of lead whose edge measures 44 cm and each bullet being 8 cm in diameter |
| Answer» TOTAL number of bullets be xRadius of a spherical BULLET = 4/2 cm = 2cmVolume of a spherical bullet = 4/3 π X (2)³ cm³ = (4/3 x 22/7 x 8)VOLUME of x spherical bullets = {4/3 x 22/7 x 8 x (x) }cm³Volume of solid CUBE = (44)³ cm³Clearly, volume of x spherical bullets = Volume of cube= [4/3 x 22/7 x 8 x (x) ] = (44)³ cm³= [4/3 x 22/7 x 8 x (x) ] = 44 x 44 x 44∴ Total number of bullets=2541 | |
