Holes have three dimensions, except for cylindrical holes which only have two but one is a diameter. You only gave two dimensions and neither was designated a diameter
In summary, you didn't give enough information to answer you question
None it's a hole
3ft x 3ft x 1ft = 9 cubic feet of dirt will be needed.
10*13*3 = 390 cubic inches.
hmm that's a tough one maybe 24' by 2' by 10 inches worth of dirt
There is none. Because there is a hole! If you are asking how much dirt can fill the hole, then your answer is 27 cubic feet.

10-1/2 cubic yards
10*13*3 = 390 cubic inches.
There is no dirt in a hole because a hole is defined by the absence of material, in this case dirt. If you were to fill the hole with dirt, it would require 24 cubic feet of dirt to completely fill it.

0. zip. none. na-tah. Think about it. If there was a hole with dirt in it, what would that be called? Huh? I'd call it anything but a hole.
Assuming a rectangular (3-D) shape, multiply the three numbers. The answer will be in cubic feet.
16*32*6 = 3072 cubic feet is needed
