You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):

We have to solve for h:


You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is
B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!
Divide 384 by 12 then multiply it by 5 to give you 160
Subtract 4 from both sides, y = 5
We have no idea how much is one faithful of a barrel.
