Question

Find the number of lead spherical bullets of radius 1cm that can be made from a lead solid cube of each side 22cm ?

Answer 1

Answer: Sphere           cube

              r = 1 cm           a = 22 cm

no. of bullets = volume of cube/volume of sphere

= a³÷4/3πr³

= (22)²÷4/3×22/7×(1)³

= 22×22×22 ÷ 4/3×22/7

= 22×22×22×3×7÷4×22

= 11×11×3×7

= 121×21

= 2541

therefore: 2541 bullets can be made from lead solid cube.
