Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 27 (the amount of cubic feet in a yard). The final figure will be the estimated amount of cubic yards required.
Add the length at the top of the excavation to the length at the bottom of the excavation and divide by 2 to get the average length. Do the same for the width. Multiply the average length times the average width times the average depth and divide by 27.
How to calculate cubic yards? The formula: Number of Cubic Yards = Length (in feet) Width (in feet) Depth (in feet) ÷ 27. Simply multiply the three dimensions together to find the number of cubic feet, then divide by 27 to find the number of cubic yards.
For a 1:1 slope: (L – D)x(W – D)xD divided by 27 = volume in cu yds to be removed. For a 2:1 slope: (L – 2D)x(W – 2D)xD divided by 27 = cu yds to be removed. For a 1.5:1 slope: (L – 1.5D)x(W – 1.5D)xD divided by 27 = cu yds to be removed.
Grade can be found by measuring the horizontal length of an elevation, the run, and the vertical height of the elevation, the rise. Grade is expressed as rise/run, so if the rise is 25 and the run is 80 the grade is 25/80.
Once the cut or fill depth is calculated, multiply the value by the area of the grid cell. Do this for each square of the grid, then add the volumes together to determine the total cut and fill volumes for the project.
To calculate the earthwork estimate requires multiplying the area by the difference between the average of two sets of levels. Formula: Volume = Area * Difference between the average of two sets of levels.

Cubic yards are used to measure the materials we provide, such as topsoil, sand, pit run, and gravel. We’ll need to know how many cubic square yards of the product you will require for your project. This is the basic formula: length [ft] x width [ft] x depth [ft] = cubic sq.
To estimate soil volume for any area, all you need is a tape measure. “The basic formula is simple: Length x Width x Height = Volume,” says Michael Dean, co-founder of Pool Research. Then divide the number of cubic feet by 27. So one cubic yard = 27 cubic feet = 1,728 cubic inches.
A cubic yard is a measurement that is 3 feet by 3 feet by 3 feet. A cubic yard measures volume where a ton measures weight. A yard of topsoil usually weighs about 1,800 pounds and a yard of gravel usually weighs about 2,200 pounds.
Length X width X depth will give you the volume of the whole area. If you use feet, divide by 27 to convert to cubic yards.
If you take a one acre pond 200′ x 200′ and dig 10′ deep you come up with approx. 15,000 yards of material. Every depth below that in 1′ increments equals approx. 1,500 more yards of dirt that need be moved.
1% grade = 0.57 degrees = 1 cm per 100 cm = 1 inch per 100 inches = 0.125 inch per foot.
1% as a decimal is 0.01 and hence the slope is 0.01. That means for a run of pipe of a certain length the rise must be 0.01 times the length. Thus for you example, since the length of the run is 80 feet which is 80 × 12 = 960 inches the rise must be 0.01 × 960 = 9.6 inches.
The total marks for every subject is 200. First, take your mathematic marks divide it by 2, then you will get the marks for 100. Marks of physics and chemistry should be divided by 4, then you would get marks for 50 for each subject. This is the normal process to getting cutoff marks.
This method involves drawing horizontal and vertical lines over your site plan to divide it into grid cells of equal size. You then include the existing elevation and proposed elevation for each corner of the grid cells, and work out the difference between the two, as this will be cut or fill depth for that spot.
Area of the plot = Length x Width = 40 x 30 =1200 sft. Suppose we need to fill the plot by 3’5” = 3.41 feet. ∴ Depth of the plot = 3.41 feet. Volume of plot to be filled = 1200 x 3.41 = 4092 cft.
When it comes to light soil excavation, the shrink may range from 20-40% or more. Moderate soil excavation shrink ranges from 10-25%. Heavy soil excavation with deep cuts and fills shrink approximately 15% and swell around 5%. These averages are helpful to know and use as a guideline.

based on different condition loose and dense, dry and wet, moisture contents, on average a yard of dirt weighs around 2,200 pounds, for 5 yards = 5×2200 = 11000 lbs, as we know 1 short ton equal as 2000 lbs, in this regard, “how much does 5 yards of dirt weigh”, in general 5 yards of dirt weighs around 11000 lbs or 5.5 …
It is easiest to calculate volume in cubic metres or litres. To do this simply measure the length, width and depth of the area you need to fill with soil in metres and multiply the three figures together to get the volume in cubic metres.
Regarding this, “How much does dirt weigh?”, on average a cubic foot of dirt mixed of top soil can weigh 80 pounds or 0.04 short tons, in general it can be range between 74 – 110 pounds per cubic foot, dry loose dirt can weight around 76 lbs per cubic foot and while moist loose dirt can weigh around 78 lbs per cubic …
Under the United States’ Customary System, 1 yard is equal to 3 feet or 36 inches. And a cubic yard is the volume of material that fits in a space that is 1 yard wide by 1 yard deep by 1 yard high. This is important because quite a few common materials are measured in cubic yards — here are some of them: Concrete.
Full-size Pickup Trucks: Can usually handle 2 cubic yards of soil, 2-3 cubic yards of mulch, and 1 cubic yard of stone or gravel.
