Calculate the volume of the room if its height is 3m 5dm, the area of one wall is 28m2 70dm2

Calculate the volume of the room if its height is 3m 5dm, the area of one wall is 28m2 70dm2, the area of the other wall is 16m2 80dm2.

1. The area of a wall is the product of the length of the wall and its height. Dividing the wall areas known by the conditions of the problem by the height, we get the length and width of the room.

Let’s bring the data to the same units of measurement 28 m2 70 dm2 = 28.7 m2; 16 m2 80 dm2 = 16.8 m2; 3 m 5 dm = 3.5 m.

28.7 / 3.5 = 8.2 m (room length);

16.8 / 3.5 = 4.8 m (room width).

2. The volume of a room is calculated by the product of the length, width and height of the room.

8.2 * 4.8 * 3.5 = 137.76 m3.

The answer is the volume of the room is 137 m3 760 dm3.
