How much dirt is in a 5 feet deep and 3 feet wide hole?

Answer 1

As it is a hole, there is no dirt in it.

However, assuming you have a cylindrical hole 3 ft wide, the volume of dirt removed to make the hole is:

volume = π x radius2 x depth

= π x (3/2)2 x 5 cu ft

= 45Ï€/4 cu ft

≈35.34 cu ft

If your hole is a cuboid, that is it is 3 ft x 3ft by 5 ft deep, then the volume of dirt removed is:

volume = length x width x depth

= 3 x 3 x 5 cu ft

= 45 cu ft.
