BeCarlson got close using the howitworks.com method. but it's true that fuel planning/fuel burn on jets are calculated using pounds/kilos - not gallons.
For a Boeing 744, a rough rule of thumb is 24,000 lbs/hour (this is not counting reserve/contingency fuel which is carried but not usually burnt)
13.5 * 24,000 = 324,000lbs
Going by 6.7 lbs of jet fuel to a gallon (which varies based on temperature)
= 48,360~ gallons fuel burn....
Have fun with the rest
