Answer:
(a) 1852259 
(b) 489085.47 pound
Explanation:
We have given auditorium measures 35 m×30 m×5 m
We know that 1 meter = 3.28 feet
So the measure of auditorium = 35×3.28 feet ×30×3.28 feet× 5×3.28 feet
(a) So the volume of the auditorium 
Density is given as 
(b) weight of air = volume × density 
We know that 1 kg = 2.20 pound
So 222311.577 kg =222311.577×2.20=489085.47 pound

Explanation:
Distance = Total path length = 35m + 35m = 70m
Displacement = Final - Initial position = 0m
From the formula: density=mass/volume
But first, we have to convert the cm³ to m³ by multiplying the value in cm³ by 10^-6, by so doing we'll have the volume to be 0.48*10^-3cm³.
we will also need to convert the mass which is in g to kg by simply dividing by 1000 so the mass becomes 0.12kg
Now we can solve for the density using the formula I earlier stated which is the mass divided by the volume =0.12/0.48*10^-3 so the density will be 0.25*10^3kgm-3 or 2.5*10^2kgm-3
