Enter the length, width, and depth into the calculator to determine the select fill needed. This calculator can also evaluate any of the variables given the others are known.

Select Fill Formula

The following formula is used to calculate the select fill needed for a project.

SF = (L * W * D) / 27


  • SF is the select fill needed (cubic yards)
  • L is the length of the area (feet)
  • W is the width of the area (feet)
  • D is the depth of the fill (feet)

To calculate the select fill needed, multiply the length of the area by the width and the depth. Then divide the result by 27 to convert the volume from cubic feet to cubic yards.

What is a Select Fill?

A Select Fill is a type of soil or material used in construction for filling purposes. It is chosen based on its properties such as compaction, stability, and drainage, which are suitable for supporting structures or facilitating proper water flow. The composition of Select Fill can vary, but it often includes a mixture of sand, clay, and rock. It is commonly used in projects such as road construction, building foundations, and landscaping.

How to Calculate Select Fill?

The following steps outline how to calculate the Select Fill using the given formula:

  1. First, determine the length of the area (L) in feet.
  2. Next, determine the width of the area (W) in feet.
  3. Next, determine the depth of the fill (D) in feet.
  4. Next, use the formula SF = (L * W * D) / 27 to calculate the Select Fill needed in cubic yards.
  5. Finally, calculate the Select Fill.
  6. After inserting the values of L, W, and D into the formula and calculating the result, check your answer.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Length of the area (L) = 10 feet

Width of the area (W) = 5 feet

Depth of the fill (D) = 2 feet
