# Air problem?

Nov 26, 2017

$15 {m}^{3} - 19.5 k g$
$30 {m}^{3} - 39 k g$
$40 {m}^{3} - 52 k g$

#### Explanation:

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

Next, you should multiply $1.3 \frac{k g}{m} ^ 3$ and $15 {m}^{3}$ together to find the weight
$1.3 \frac{k g}{m} ^ 3 \cdot 15 {m}^{3} = 19.5 k g$

Then, you should repeat the process for each number.
