How many lead shots each 3 mm in diameter can be made from a cuboid of dimensions 9 cm × 12 cm?
Given,
Diameter of the lead shot = 3 mm
Radius (r) of a lead shot = 3/2 = 1.5 mm = 0.15 cm and
Dimensions of the cuboid = 9 cm x 11 cm x 12 cm
Now,
The number of the lead shots =
= 84000
So,
84000 number of lead shots can be made from the cuboid.
