Question

A dining hall has dimensions 50 m × 15 m × 3.5 m. Calculate the mass of air in the hall, when density of air is 1.30 kgm$^{–3}$​

Answer 1

Answer:

Given:-

Dimensions of dining hall = 50 m × 15 m × 3.5 m.

Density of air

$= 1.30 \: kgm {}^{ - 3}$

To find:-

Mass of air in the hall.

Solution:-

We know that,

Mass of air = Volume × Density

$= 2625 \: m {}^{3} \times 1.30 \: kg \: m {}^{ - 3} \\ \\ = 3412.5 \: kg$

Thus, mass of air in the hall = 3412.5 kg
