Answer 2

Given, length = 18 m, breadth = 12 m and height = 8 m

Finding the area of the four walls of the room is also known as finding the Lateral Surface Area of the room.

We know that the lateral surface area of a cuboid = 2h (l + b) where, h is the height, l is the length and b is the breadth of the cuboid.

Lateral Surface Area of the given cuboid = 2(8) (18+12) = (16)(30) = 480 sq.m

Answer:

The area of the four walls of the room is 480 sq.m .
