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 dimensions are given to 3 sig fig
... that's what the answer should have

1 m^3 = (3.28 ft)^3

v = 43 * 18 * 15 * 3.28^3 ft^3

... use 3 significant figures in the answer

Answer 2

ok i got it, thanks.
4.10*10^5
