Question

calculate the mass of air in a room with internal measurement 6 metre by 4 metre by 9 metre if the density of air is 1.3 m³​

Answer 1

9.4.6=216

216.1,3=280

Explanation:

Answer 2

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

We know,

`\boxed{volume = l * b * h}`

so,

`\hookrightarrow{volume = 6 * 4 * 9}`

`\hookrightarrow volume = 216 \: m {}^(3)`

now,

`\boxed{density = (mass)/(volume) }`

So,

`\hookrightarrow1.3 = (m)/(216)`

`\hookrightarrow \: m = 216 * 1.3`

`\hookrightarrow \: m = 280.8`

hence, mass of air in the room is 280.8 kg
