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.
How do you calculate soil removal volume?
Simply multiply the length by the width by the depth or use our simple volume calculator. Circular areas are also easy to calculate. Simply multiply 3.1415 (π) by the radius, by the radius again, by the depth or use our simple volume calculator.
What is the formula for dirt?
“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.
How do you calculate excavation?
So, the formula is: Ab = Wb * Lb, where Wb and Lb are the width and length of the bottom of the excavation. At = Wt * Lt, where Wt and Lt are the width and length of the top of the excavation. In our example, Wb = Lb = 5 and Wt = Lt = 15, so Ab = 5 * 5 = 25 and At = 15 * 15 = 225, and D = 5.
How do you calculate topsoil excavation?
To calculate how much topsoil you need, simply measure the dimensions of the area you wish to cover and multiply this by the depth required. Measuring in metres is simplest, as this will give you the volume of topsoil you need in cubic metres.
How is earth excavation calculated?
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.
How do you calculate soil filling?
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.
How do I figure out how many yards of dirt I need for a pile?
Calculating the cubic yards in a pile of dirt first requires the homeowner to figure the size of the cone using this formula: V = 1/3 * π * R² * H. V = the volume in cubic feet. π = 3.14159265. R² = length B divided by 2. H = Height.
How do I calculate yards of dirt?
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.
How much dirt do I need to level my yard?
Calculate How Much Soil You Need Convert the inches you need for soil depth into feet. Example: 3″ of soil (3″ ÷ 12″=.25′) Multiply the length by the width by the depth of soil needed. Divide the cubic feet by 27 (that’s the number of cubic feet in one cubic yard). Round off your answer to 1.4 cubic yards.
How do you calculate cut and fill soil?
The cut or fill depth for each cell is found by subtracting the average existing level of the cell from the average proposed level. If the resultant depth is positive then this is a fill cell, while a negative value indicates a cut cell.
How do you calculate slope of excavation?
For example, if the trench is 6 ft deep and 20 ft wide across the end of the trench and the bottom of the trench is 2 ft wide, the slope can be calculated as follows: Horizontal distance = 20 ft – 2 ft ÷ 2 = 9 and the Vertical depth = 6 ft; Slope = 9 ÷ 6 = 1.5 to 1, which is the slope needed for type C soil.
What is a bulking factor?
The bulking factor is the ratio or percentage of the volume change of excavated material to the volume of the original in situ volume before excavation. The bulking factor is used to estimate the likely excavated volumes that will need to be stored on site or perhaps removed from site.
How much topsoil depth do I need?
Turf ideally needs around four inches of top soil to root in. Not everyone will need to add four inches however, you may just need to add an inch or two depending on the quality and depth of the existing soil.
How do you calculate soil bulking factor?
To use a bulking factor number you have to multiply the bulking factor number by the excavated volume size. If your excavation was 15 m3. You must consider the bulking factor of the material you are digging to ensure you correctly plan for the removal costs and time to do it in.
How do you calculate backfill and excavation?
Backfill for Figure 3.1: Backfill volume = excavation volume – footing volume – wall volume. (Note that only the portion of the wall that is in the trench is deducted, so the height of wall in the trench is the average trench depth minus 2′-0” for the footing: 6′-0” – 2′-0” is 4′-0”) Backfill volume = 207.4 cubic yards.
How do you calculate backfill?
For example, find the cubic footage volume of a backfill area that is 8 feet wide, 6 feet deep and 50 feet long. The volume of a rectangular cubed shape is found by the formula v = l x w x d, where v represents volume, l is the length of the trench, w is the width and d is the depth.
How is pile area calculated?
Pile concrete volume is calculated with the subsequent formula: πr 2 h (here, r indicates pile radius and h indicates pile height) Therefore, concrete volume = πr 2 h x 3 (since there are three numbers pile caps).
How many tons is 100 cubic yards?
27 ton Cubic Yard [yd^3] Ton Register [ton Reg] 20 yd^3 5.4 ton reg 50 yd^3 13.5 ton reg 100 yd^3 27 ton reg 1000 yd^3 270 ton reg.
