36 cubic feet of dirt=)
cylinder 18 feet diameter x 1.5 feet deep volume = 381 cubic feet
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
if you mean a 30 foot diameter circle, then pi x 152 x 3 = 2119.5 cubic feet of dirt
39,600 cubic feet. 1,466 cubic yards or about 122 truckloads if it were non-compacted fill.
300 cubic feet of dirt
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
Assuming 20 feet by 40 feet, 20x40x4 = 3200 cu ft = 3200/27 = 120 yards = 320,000 pounds
There is no dirt in a hole that is 3 feet deep and six inches in diameter.
16 sq ft*0.5 ft = 8 cubic feet.
There is no dirt in a hole because a hole is defined by the absence of material, in this case dirt. If you were to fill the hole with dirt, it would require 24 cubic feet of dirt to completely fill it.
24 feet
To fill a hole 2 feet long, 4 feet wide, and 6 feet deep would take 48 (2 x 4 x 6) cubic feet of dirt.
