Question

10m^3 of air weigh 13 kg

How much does the air weigh in a room 4.2m long, 3.5m wide, and 2.6m high?

Answer 1

The weight of air in the room is 49.69kg

Step-by-step explanation:

First of all we have to calculate the volume of the air present in the room.

Here

Length = 4.2m

Width = 3.5m

Height = 2.6m

The volume of the air in the room is:

$V = Length*Width*Height\\= 4.2*3.5*2.6\\=38.22\ m^3$

Now we have to find the density of the air

Density is the mass of a matter in per unit of volume

Density = 13/10 = 1.3 kg/m^3

So the weight of air is:

$Volume * Density\\= 38.22*1.3\\=49.686\\=49.69\ kg$

The weight of air in the room is 49.69kg
