Room height 2 m 50 cm, width 4 m, length 6 m 5 dm How many cubic meters of air is in the room?

First, let’s translate all values into meters. 1 m is equal to 100 cm. 1 m is equal to 1 dm.

2 m 50 cm = 2.5 m.

6 m 5 dm = 6.5 m.

Let’s calculate the volume of air in the room. To determine the volume, the length of the room must be multiplied by its width and by its height.

V = 2.5 * 4 * 6.5 = 65 m3.

Answer: the volume of air in the room is 65 m3.
