Question

A room has its dimensions of 5m x 4m x 3m. Density of air is 1.3 kg/m3. What is the mass of air in the room?

Answer 1

Answer:

Explanation:

Dimensions of room are 5m 4m and 3m

Thus volume of room = 5 x 4 x 3

= 60 m^3

We know that Density = Mass/Volume

1.3 = Mass of air / 60

Mass of air = 1.3 x 60 = 78 kg
