how many lead shots each 3 mm in diameter can be made from a cuboid with dimension 12 cm × 11 cm × 9 CM ?

Answered by admin @ 20/08/2021

Volume of the cuboid= 12×11×9
= 1,188cm^3

Volume of the lead shot= 4/3πr^3
= 14.14mm^3
= 0.01414cm^3

No.of lead shots = volume of the cuboid/ volume of the lead shot
= 1188/0.01414
= 84,016.9731
