Question

D
Calculate the mass of air in a room if the floor dimensions are 10 m
12 m and height 4 m. The density of air is 1.26 kgm-3

Answer 1

Answer:

The Volume of the room is given as V=LxBxH=5x3x4=60m

3

We know, Mass = Density Volume. Given that the density =1.3kg/m

3

So, Mass of the air =1.3x60Kg. Hence, mass of the air enclosed in the room is 78 kg.
