Question

An aquarium is in the form of a cuboid whose external measures are
80 cm × 30 cm × 40 cm. The base, side faces and back face are to be covered with a coloured paper. Find the area of the paper needed?plz faaast

Answer 1

Given l = 80,b=30,h=40.

Area of the base = l * b = 80 * 30 = 2400

Area of the side faces = b * h = 30 * 40 = 1200

Area of the back face = 80 * 40 = 3200.

Total Area = 2400 + 3200 + 2(1200)

                  = 8000.


Hope this helps!
