Soil Calculation Formula

The calculator uses a standard soil volume formula to determine accurate measurements.

Cubic Feet Formula

Cubic Feet=Length×Width×(Depth12)\text{Cubic Feet} = \text{Length} \times \text{Width} \times \left(\frac{\text{Depth}}{12}\right)Cubic Feet=Length×Width×(12Depth​)

Since depth is entered in inches, it is divided by 12 to convert it into feet.

Cubic Yards Formula

Cubic Yards=Cubic Feet27\text{Cubic Yards} = \frac{\text{Cubic Feet}}{27}Cubic Yards=27Cubic Feet​

One cubic yard equals 27 cubic feet.

Total Cost Formula

Total Cost=Cubic Yards×Price Per Cubic Yard\text{Total Cost} = \text{Cubic Yards} \times \text{Price Per Cubic Yard}Total Cost=Cubic Yards×Price Per Cubic Yard


Example Calculation

Let’s say you have a raised garden bed with the following dimensions:

  • Length: 8 feet
  • Width: 4 feet
  • Depth: 10 inches
  • Soil Price: $50 per cubic yard

Step 1: Calculate Cubic Feet

8×4×(1012)=26.67 ft38 \times 4 \times \left(\frac{10}{12}\right) = 26.67\ \text{ft}^38×4×(1210​)=26.67 ft3

Step 2: Convert to Cubic Yards

26.6727=0.99 yd3\frac{26.67}{27} = 0.99\ \text{yd}^32726.67​=0.99 yd3

Step 3: Calculate Cost

0.99×50=49.50.99 \times 50 = 49.50.99×50=49.5

Final Results

  • Cubic Feet Needed: 26.67 ft³
  • Cubic Yards Needed: 0.99 yd³
  • Estimated Cost: $49.50
