It's cubic centimeter per minute
I don't understand very well what I have to do...What I did before was v= P/W P= (mu(mg)+(1/2)(CD)(rho)Sv^3) w=36.0 MJ*20% V=((mu(mg)+(1/2)(CD)(rho)Sv^3)/ (36x10^6 *0.2) I plugged in the values and got .00217 L/s and then to get the gas mileage=(0.00218^-1

Oh ok... thanks a lot, I was typing 12 all this time....
I'm sorry, yeah it's ((2-h)^3 - 8)/h
I tried and I got -1.17 for one of them... I plugged both answers and I just got the g(2) right, I'm not sure what to do now....
