Question

The density of air is 1.3kg/m3 calculate the mass of air in the room

Answer 1

Answer:

The volume of the room is as V = L×B×H = 5×3×4 = 60m3

we know, Mass = Density × Volume.

Given that the density = 1.3kg/m3.

So, Mass of the air = 1.3×60kg.

Hence, Mass of the air enclosed in the room is 78kg.
