How many metal doorstops 15 cm by 10 cm by 5 cm can be cast from a spherical ball of metal of diameter 400 mm?

Step-by-step explanation:

Given

Diameter of spherical metal ball = 400 mm = 40 cm

Radius of spherical metal ball = 20 cm

Volume of a sphere is given as:

Dimensions of metal doorstops = 15 cm by 10 cm by 5 cm

It is of cuboid shape.

Volume of a cuboid is given as:

Number of such doorsteps that can be made from the metal ball is equal to Volume of metal ball divided by volume of metal doorstep.
