Answer:
(a) 1852259 [tex]ft^3[/tex] (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 [tex]=35\times 3.28\times 30\times 3.28\times 5\times 3.28=185259.648ft^3[/tex]
Density is given as [tex]d=1.20kg/m^3[/tex]
(b) weight of air = volume × density [tex]=185259.648\times 1.2=222311.577kg[/tex]
We know that 1 kg = 2.20 pound
So 222311.577 kg =222311.577×2.20=489085.47 pound
