1. What is the 100 Square Feet Soil Calculator?

This calculator determines the volume of soil needed (in cubic yards) to cover a 100 square feet area to a specified depth. It's useful for gardening, landscaping, and construction projects.

2. How Does the Calculator Work?

The calculator uses the soil volume formula:

\[ Soil\,(yd³) = 100 \times Depth\,(ft) \div 27 \]

Where:

Explanation: The formula converts the volume from cubic feet to cubic yards, which is the standard measurement for bulk soil purchases.

3. Importance of Soil Volume Calculation

Details: Accurate soil volume estimation helps in purchasing the right amount of soil, avoiding both shortages and costly overages for your projects.

4. Using the Calculator

Tips: Enter the desired depth in feet (e.g., 0.5 for 6 inches). The calculator will show the volume in cubic yards needed for a 100 square feet area.

5. Frequently Asked Questions (FAQ)

Q1: How do I adjust for different area sizes?
A: Multiply the result by your actual area divided by 100. For example, for 200 sq ft: double the result.

Q2: What's a typical depth for garden beds?
A: Most gardens need 6-12 inches (0.5-1 foot) of quality topsoil. Lawns typically need 4-6 inches.

Q3: How many bags of soil equal a cubic yard?
A: About 13.5 bags of 2 cubic feet each make 1 cubic yard (since 27/2 = 13.5).

Q4: Should I account for soil compaction?
A: Yes, add 10-15% more for compaction, especially for deeper applications.

Q5: How much does a cubic yard of soil weigh?
A: Typically 1,000-1,500 lbs depending on moisture content and composition.
