An auditorium measures 40.0 m X 20.0 m X 12.0 m. The density of air is 1.20 kg/m3. What are (a) the volume of the

room in cubic feet and (b) the weight of air in the room in pounds?

volume = 339008 cubic feets

weight = 25397.253 pounds

Explanation:

a) 1 feet = 3.2808 m

volume = length*breath*height

(40*3.2808) * (20*3.2808) * (12*3.2808

=339008 cubic feets

b) weight = volume * density

= (40*20*12) * 1.20

= 11520 kg

= 25397.253 pounds
