Question

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

Answer 1

FIRST WE FIND VOLUME OF BOTH BULLET AND THE CUBE OF LEAD
VOLUME OF BULLET=4/3πR³
                                =4/3×22/7×(2)³
                                =704
VOLUME OF CUBE LEAD=A³
                                      =(44)³
                                      =85184
NOW,
                VOLUME OF CUBE/VOLUME OF BULLET=NO. OF BULLET
                    =85184/704
                    =121
NO. OF BULLET=121
