Question

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? ​

Answer 1

volume = 339008 cubic feets

weight = 25397.253 pounds

Step-by-step 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
