None. You have only given an area and no depth. Without a depth, the volume is zero and thus the hole does not exist and no gravel will be needed. If you meant a round hole 12 ft by 14 ft it is still unclear as to the dimension of the hole: firstly which is the depth (the 14 ft is the most likely), but when speaking of a round hole would you mean the perimeter, the radius or diameter for the given measurement? They all lead to different volumes and hence difference amounts of gravel needed to fill the hole. Ans 3 - 12 x 14 is NOT round it is rectangular
if you mean a 30 foot diameter circle, then pi x 152 x 3 = 2119.5 cubic feet of dirt
If you multiply 30 x 16 you should get a good approximation...
