None. It's a hole. The earth has already been removed. If you remove any more, it's a different size hole.
36 cubic feet None, unless you want to make the hole bigger. However, as someone who's just dug a hole and was amazed at how many rubble bags I needed to fill to get rid of it. It certainly feels like more than the maths would suggest. I have heard that earth expands as it's removed as it's no longer under pressure so you can assume a 40% greater volume once it's out of the ground. So in pure terms it's 36 cubic feet, but if you're digging your garden, allow for more. Frizzboo123 says: Earth Can't Be Removed From A HOLE.
none, its a hole.
very deep about 2 and half feet or three
125 cubic feet
You are buried 6 feet underground nowadays
There is no dirt in a hole, as a hole is an empty space where dirt has been removed.
None. The size of the hole is a measure of space in which there is no dirt!
THREE TO FOUR FEET
Averages three to ten feet.
If they are in tree-tops, they are about three feet deep and eight- to ten-feet in diameter.
None because it is an empty space of 12 cubic feet
Width of hole: 6510/(40*10.6) = about 15 feet to the nearest integer
