Question
A metal container has external dimensions of 30 cm in
length, 25 cm in width, and 20 cm in height. The thickness of the metal is 2 cm. Calculate the volume of metal used to make the container.Solution
l=30, b=25, h=20, and x =2 Volume of hollow cuboid = l× b× h –(l-2x) (b-2x) (h-2x) --where, x is the thickness of walls of the cuboid = 30×25×20 – (30-4) (25-4) (20-4) =15000-26×21×16 =15000-8736 = 6264cm3
