Question

If the density of air is 1.3 kg/ cubic meter .The mass of air in room 8m5xmx4m is​

Answer 1

Answer:

208 kg

Step-by-step explanation:

density = 1.3kg/m^3

volume=8×5×4=160m^3

density= mass/volume

1.3=m/160

m=160×1.3

m=208kg

Answer 2

Density=Mass/Volume

Mass=Density×Volume

Here,

Density=1.3 kg/m^3

Volume=8×5×4 m^3

So,

Mass=1.3×8×5×4

=208kg

So,

The mass of air in a room of dimensions 8m×5m×4m will be 208 kg.
