That's right. All that are left are three-gallon buckets and
eight-gallon
buckets. Your task is to describe how to measure eleven quarts of
gasoline.

You fill one eight-gallon bucket and one three-gallon bucket.

Oh, sorry, that gives you eleven _gallons_ of gasoline. Since the
sizes of the buckets are all multiples of one gallon, and eleven
quarts of gasoline is not a multiple of a gallon, the proposed task is
provably impossible.

Hm. We can get half-gallons fairly easily, but I don't see an immediate
way
to get quarter-gallons, or "quarts" in the vernacular.

Get your half-gallon and split it evenly between two buckets. Presto.
You now have quarts.

You are assuming that you have at least pairs of 3 gallon buckets
with exactly the same height and the same top and bottom diameters
(and the same for 8 gallon buckets).

There are enough silly-ass restrictions on this "problem" without imagining more. The parameters offered don't include all-different bucket shapes.

I mean, the problem also assumes that you have a way to open the underground tanks, and have a tube to siphon gas through; it doesn't say for sure.

But if they do, rig a scale, balance them by weight, not eye.
