Is it true that buses have a 200 gallon tank capacity and airplanes 10k gallon tank?

Question

I found out just by reasoning

Answer 1

Yes buses have about 200 gallons . The 747 aircraft holds 57,000 gallons.

Answer 2

It depends on the type of bus and the type of aircraft. Most buses, I believe, have two tanks with each holding about 100 gallons.

For airplanes, there is a large difference. For a Boeing 747, there are even extra optional fuel tanks. Most large planes such as that actually use a large part of the wings as a fuel tank. The 747 holds about 57,000 gallons per engine (there are 4 engines).
