Soil Calculation Formula
The calculator uses a standard soil volume formula to determine accurate measurements.
Cubic Feet Formula
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=27Cubic Feet
One cubic yard equals 27 cubic feet.
Total Cost Formula
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×(1210)=26.67 ft3
Step 2: Convert to Cubic Yards
2726.67=0.99 yd3
Step 3: Calculate Cost
0.99×50=49.5
Final Results
- Cubic Feet Needed: 26.67 ft³
- Cubic Yards Needed: 0.99 yd³
- Estimated Cost: $49.50
