The good answer is d) 14.2 m³.

The common conversion factor that everybody knows is "1 m = 39.37 in".

You can use this to convert feet to inches and then to metres.

#"500 ft"^3 × ("12 in"/"1 ft")^3 × ("1 m"/"39.37 in")^3 = "14.2 m"^3#

Notice that we have to cube the conversion factors to make the units "ft³" and "in³" cancel.
