The density of air is 1.29 kg/m^3.
What is the mass of air in a room
that is 4.50 m x 7.88 m x 13.0 m?
(Unit = kg)

The answer is 525

Mass of air is 594.66 kg

Explanation:

We have,

The density of air is

Dimension of the room is 4.50 m x 7.88 m x 13.0 m

Volume of the room is

The density of an object is given by mass per unit its volume. Its mathematical form is given by :

m is mass of air in a room

So, the mass of the air in a room is 594.66 kg.
