It's not too difficult to know or calculate inches in a mile:
12 * 3 * 1760 = 12 * 5280 = 63,360
A few Americans may know how many cubic inches in a US gallon:
231
But I don't believe anyone (apart from rainman/prodigy circus performers) can do this in their head:
63360^3 / 231 = 1,101,117,147,428.571
Estimate yes; calculate no.
