please explain the answer in step by step.
Who will give me correct answer I will mark them brain list answer​

Answer 1

Answer:

The Volume of the room is given as V=L×B×H=5×3×4=60m

3

.

We know, Mass = Density×Volume.

Given that the density =1.3kg/m

3

.

So, Mass of the air =1.3×60Kg.

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