How many yards of fill dirt in area 25x40x4 inches thick?

Answer 1

You find the square footage of the total area....40 X 60=2400 square feet. Then convert that to cubic yards by dividing by 27....(27 cubic feet per cubic yard) 2400 divided by 27= 85.1 cu. yards To raise the area by one foot, this would be the end of the calculation. If you were to only want to raise an area by 4 inches lets say....then you would multiply 85.1 by .33 or one third of a foot. (for 6 inches you would multiply by .50 or 1/2 foot) NOW, you have to take into account compaction or loss. When figuring concrete, allow up to 10%. When figuring dirt (depending on how sandy etc.) rule of thumb is to allow UP TO 1/3 for compaction. In your question above, allow for 1/3 and you would need another 28 yards (cu. yards). This would figure as 85.1 X.33 and would equal roughly another 28 yards. So, the total needed would be 85 cu. yds (85 rounded) PLUS 28 .....or a total of 113 cu. yards.

Answer 2

if its a hole, then i would say there are zero cubic yds of dirt. other wise its 16 * 14 * 9 / 27 = 74.667 cubic yds of dirt you divide by 27 because there are 27 cubic feet in a cubic yd

Answer 3

You need 5 1/3 yards of dirt 10 feet wide and 2 inches deep which is approx 0.99 cubic yards
