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
