This question is about a cubed area. First convert the inches to feet--18 inches is 1.5 feet. Then multiply all three numbers by each other. 15*12*1.5 is 270. You will need 270 cubed feet of dirt to fill the area.
2.37 cubic yards of dirt is needed to fill an 8'X4' that is 24" deep garden box. If the box is filled 12 inches, the amount of soil needed is 1.19 cubic yards and that should be deep enough for most vegetables.
Sorry the first answer was in square yds. Cubic yards would be 0.308639
First of all divide 2" by 12" to get 0.1666 feet; then multiply 0.1666' x 40' x 40' which equals 266.56 cubic feet; Multiply 266.56 cubic feet x 0.03704 to get 9.8734; Therefore, 2 inches of topsoil from an area 40 feet by 40 feet = 9.87 cubic yards. Hope that helps. The number 0.03704 is purely a conversion rate for cubic feet to cubic yards.
133.33 cubic yards, that's 400 feet
Trees, bushes, dirt, water
There is no dirt in a hole that is 3 feet deep and six inches in diameter.
You will need 1500 cubic feet.
none there is no dirt in a hole
None. There is nothing in a hole.
None! If there was dirt in it then it wouldn't be a hole.
none.

You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.
806.66 Cubic Yards
None but the volume of space taken can be calculated
At 3 inch deep and 27 foot round that is 3.14 x 27x27x3/12/4 = 143 cubic feet which is 143/27 = 5.3 yards. At 100 pounds/cu ft that weighs 14,300 pounds of dirt
Just multiply 1/2 foot x 12,000 square feet. The answer will be in cubic feet.
