| **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.

Will:

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

Answer:

Wall area 79.704 m2, room volume 118.9718 m3
