Question

A dining hall has dimensions : 50 m * 15 m * 3.5 m . Calculate the mass of air in the hall ( density of air = 1.30 kg/m^3)

Answer 1

@ghazi

Answer 2

mass = volume *density = 50*15*3.5*1.30 kg this should be the answer but it doesnt seem to me reasonable :(

Answer 3

@ghazi got it :

\[\large{Density _ \textbf{air} = \frac{\textbf{mass of air}}{\textbf{Volume of air}}}\]
\[\large{Density_\textbf{air} = \frac{\textbf{mass of air}}{\textbf{Volume of dining hall}}}\]

so I got it now

Answer 4

thanks @ghazi

Answer 5

It seems reasonable to me :P

Answer 6

you are welcome but always focus on the thing that your answer is reasonable

Answer 7
