Question

An auditorium measures 43.0m × 18.0m × 15.0m. The density of air is 1.20 kg/m3. What is the volume of the room in cubic feet? (Do not input units. Note that 1m = 3.28ft)
My Answer 43x18x15 = 11,610 m^3 11,610m3 * 3.28ft m = 38,080.8 ft When I used this number I got it incorrect and it said for me to use less figures

Answer 1

The question here would be what is the volume of the room. The density of air that is given has no use. We simply multiply the dimensions given of the room to determine  the volume.

43.0m × 18.0m × 15.0m = 11610m^3 ( 3.28 ft / 1 m)^3 = 4.09 x 10^5 ft^3
