$\huge\hookrightarrow \mathbb{ \color{gold}Answer}$

We know,

$\boxed{volume = l \times b \times h}$

so,

$\hookrightarrow{volume = 6 \times 4 \times 9}$

$\hookrightarrow volume = 216 \: m {}^{3}$

now,

$\boxed{density = \frac{mass}{volume} }$

So,

$\hookrightarrow1.3 = \dfrac{m}{216}$

$\hookrightarrow \: m = 216 \times 1.3$

$\hookrightarrow \: m = 280.8$

hence, mass of air in the room is 280.8 kg

Use calculator for the solving:

12 / 24 - 3/216 +5600 -5554 = ?

46.4861111111

Hopefully it's correct :)
