A car travels a distance of 240 miles using 8 gallons of fuel. Another car, similar in shape but larger, has dimensions scaled up by a factor of 1.5. If the larger car has the same fuel efficiency in terms of miles per gallon but its fuel consumption is proportional to its surface area, how many gallons of fuel will the larger car consume to travel 360 miles? Let's think step by step and output the final answer within \boxed{}.
