Find the sum of the areas of all the walls of the room if the room is 7.2 m long, 5.1 m wide, and 3.24 m high.Find the volume of the room.
In order to determine the volume of a room, it is required to multiply the length, width and height of the room among themselves.
Thus, we get:
V = 7.2 * 5.1 * 3.24 = 118.9728 m3
Determine the area of the long walls.
We multiply the number of walls, namely 2, by the length and height of the room.
2 * 7.2 * 3.24 = 46.656 m2
Find the area of the short walls.
2 * 5.1 * 3.24 = 33.048 m2
We find the total area of the walls of the room.
46.656 + 33.048 = 79.704 m2
Wall area 79.704 m2, room volume 118.9718 m3
