Question

Air problem?

Answer 1

`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.
