Air volume of 1m2 contains 0.21 m3. My room is 4.4 m long, 4 m wide, 2.7 m high

Air volume of 1m2 contains 0.21 m3. My room is 4.4 m long, 4 m wide, 2.7 m high. Calculate the amount of oxygen in the room.

According to the condition of this task, it is required to perform calculations and determine the amount of oxygen in a given room. Since we know that a volume of air of 1 m3 contains 0.21 m3 of oxygen, then to calculate the volume of oxygen in a room, it is first necessary to calculate the volume of air in the room.

4.4 * 4 * 2.7 = 47.52 m3;

Now let’s make a proportion to calculate the volume of oxygen in the volume of air in the room:

1m3 of air -> 0.21m3 of oxygen;

47.52 m3 air -> x m3 oxygen;

We solve the proportion using the cross method:

x = 47.52 * 0.21 / 1 = 9.9792 (m3 of oxygen).

Answer: The given room will contain 9.9792 m3 of oxygen.
