UFOs must be incredibly fuel-efficient if they are able to traverse the deep ends of space in such a small spacecraft. One UFO is said to have a fuel efficiency of 7.2 zorps per flerg, where 1 zorp is an alien unit of length equal to 2.7 light years, and 1 flerg is an alien unit of volume equal to 1.5 cubic meters. What is that UFO's fuel efficiency in miles per gallon? Express your result in scientific notation with three significant figures using E-notation. Note: 1 light year = 5.88 E12 miles 1 cubic meter = 264 gallons
