Question

The dimensions of a hall are 10 m X 7 m X 5 m. If the density of air is 1.11

kg m¯3

, find the mass of air in the hall.


plz answer this ASAP

Answer 1

$volume = 10 \times 7 \times 5$

$volume = 350 {m}^{3}$

Given:-

$density = 1.11 \: kg {m}^{ - 3}$

as we know,

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

putting value,

$1.11 = \frac{mass}{350}$

$mass = 1.11 \times 350$

$mass = 388.5 \: kg$

mass of air in hall = 388.5 kg
