10. The fuel gage for a gasoline tank in a car reads proportional to the bottom gage pressure as in Fig.1. If the tank is 30 cm deep and accidentally contains 2 cm of water plus gasoline, how many centimeters of air remain at the top when the gage erroneously reads "full"? Hint: The gage reading "full" refers to the tank when full entirely with gasoline.
