Question

Calculate the density of air , if mass of air is 1 kg and volume of the room with length 10m , breadth 2m and height 5m.​

Answer 1

78 kg

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.e room wit

Answer 2

Answer:

0.01 kg/m³

Explanation:

Volume = l x b x h

              = 2 x 10 x 5

              = 100m³

Mass = 1 kg

Density = mass/volume

              = 1/100

= 0.01kg/m³ or 10 g/m³
