15m^3 - 19.5kg
30m^3 - 39kg
40m^3 - 52kg

Explanation:

I would start off by doing 13 ÷ 10 so you can find the kg of air per m^3
13kg ÷ 10m^3 = 1.3kg of air per m^3

Next, you should multiply 1.3(kg)/m^3 and 15m^3 together to find the weight
1.3(kg)/m^3 * 15m^3 =19.5kg

Then, you should repeat the process for each number.
