there is no dirt in a hole that has been dug. there is just a hole....
But assuming you mean how much dirt was in the hole:
I am assuming that the whole is circular and the width is the diameter of the whole.
To find the cubic feet of dirt in a hole you need to find the volume. The formula for volume of a cylinder (a 3-D shape with circles at two ends aka a can) is:
V = PI * r^2 * h
V = volume
PI = the constant PI which is about equal to 3.14
r = the radius of the hole or 1/2 the diameter
h = the height of the cylinder, or depth of the hole in this case
Plugging in your numbers and solving for V
V = 3.14 * (7/2) ^2 * 3
V = 115.395 cubic feet
None. It's a hole. 162 cubic feet of air. There is no dirt in a hole.
No dirt because its a hole
96 cubic feet
This is probably a trick question: there is no dirt in a hole. However, the hole was originally filled in with 24 cubic feet of dirt.
There is 98.17477042 cubic feet of dirt in a 5 foot deep hole that is 5 foot across.
There is no dirt in a hole. If the hole is being dug, the amount of dirt being removed would be equal to the volume of the hole, which is 3 feet wide, 5 feet across, and 6 feet deep. So, the volume of dirt being removed would be 3 x 5 x 6 = 90 cubic feet.
Noe but it can be filled in with 12 cubic feet of dirt
125 cubic feet
None, it's a hole, remember? 1 cubic yard of dirt has been removed to create this hole.
None, if you dug the hole, you emptied it of 162 square feet of dirt, so put it back.
504 cubic feet
None because it's a hole but 6 cubic yards of dirt will fill it up.
