Assuming a rectangular (3-D) shape, multiply the three numbers. The answer will be in cubic feet.
10-1/2 cubic yards
10*13*3 = 390 cubic inches.
The question cannot be answered in a sensible way. The size of the hole is given in only two dimensions - in all likelihood, that means the area that the hole covers but not how deep it is. The amount of dirt required to fill the hole will depend on the depth of the hole as well.
None it's a hole
There is NO dirt, it is a hole! If you want to fill it with dirt, that is 4x6x12=288 cubic feet, weighing about 28,800 pounds
None because it's a hole but 6 cubic yards of dirt will fill it up.
3ft x 3ft x 1ft = 9 cubic feet of dirt will be needed.
A hole does not have dirt!
There is no dirt. It's a hole.
6,400 ft3
Theoretically, none. The amount of dirt excavated to create such a hole would be 1 cubic metre. However, excavated dirt (depending on the nature of the dirt) can increase in mass by up to a third the original size. That is why when you dig a big hole then fill it in (getting all the dirt back) the hole is raised on top not flat.
