John Fields is pretty astute, and engineers learn early not to answer
general questions with specifics. "How much paint does it take to paint
a door?" should be immediately replied to with "How big is the door, and
what sort of paint?", because any specific answer is only going to be
correct if the questioner and respondent both share all the same
assumptions.

Oh shoot, that's easy. "A cup" - you may have to thin it a bit to
cover the whole door, but a cup will paint it.
For a more precise answer: If you are going to paint just one
side, then half as much as to paint both sides. Conversely, twice as
much to paint both sides as you'd need for one side.
For more precision, you can mark out a scale representation on the
wall of the door, paint it, and the scale up the quantity needed.
Of course, all this presupposes that the inquirer wants to apply
paint to the entire door, and not just put some paint on the door.

It is like determining how long is a piece of string: Hold by both
ends, flip it up in the air, guess how high up the mid-point is, and
then double it.

(Similar as to hear how Frislanders weigh pigs.]

Go not to the Net for answers, for it will tell you Yes and no. And
you are a bloody fool, only an ignorant cretin would even ask the
question, forty two, 47, the second door, and how many blonde lawyers
does it take to change a lightbulb.
