Soil Volume Formula Explained
The calculator uses standard volume formulas to ensure accurate soil estimation.
Cubic Feet Formula
Cubic Feet=Length×Width×(12Depth)
The depth is divided by 12 because it is entered in inches and converted into feet.
Cubic Yards Formula
Cubic Yards=27Cubic Feet
There are 27 cubic feet in one cubic yard.
Total Cost Formula
Total Cost=Cubic Yards×Price Per Cubic Yard
Example Garden Soil Calculation
Suppose you have a raised garden bed with the following dimensions:
- Length = 10 feet
- Width = 4 feet
- Depth = 12 inches
- Soil Price = $50 per cubic yard
Step 1: Calculate Cubic Feet
10×4×(1212)=40 ft3
Step 2: Convert to Cubic Yards
2740=1.48 yd3
Step 3: Calculate Total Cost
1.48×50=74
Final Results
- Cubic Feet Needed: 40 ft³
- Cubic Yards Needed: 1.48 yd³
