Answer:

The weigh of air in the room having volume 38.22 m³ is 49.68 kg  

Step-by-step explanation:

Given as :

Length of room = 4.2 m

Width of room = 3.5 m

Height of room = 2.6 m

So ,  volume of room = Length × Width × Height

Or,   volume of room = 4.2 m × 3.5 m × 2.6 m

∴,     volume of room = 38.22 m³

Now,

∵  10 m³ of air weigh 13 kg

so, 1 m³ of air weigh =  \frac{13}{10} kg

∴    38.22 m³ of air weigh = \frac{13}{10} kg × 38.22 kg

I.e 38.22 m³ of air weigh = 49.68 kg

Hence The weigh of air in the room having volume 38.22 m³ is 49.68 kg  Answer
