1. What is the Sand and Gravel Calculator?

This calculator helps determine the volume and weight of sand or gravel needed for a project based on area, depth, and material density. It's essential for landscaping and construction projects.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( Area \) — Surface area in square feet
• \( Depth \) — Depth in feet
• \( Density \) — Material density in pounds per cubic foot (sand ≈ 100 lb/ft³, gravel ≈ 105-125 lb/ft³)

3. Importance of Accurate Calculations

Details: Proper calculation ensures you order the right amount of material, avoiding costly over-ordering or project delays from under-ordering.

4. Using the Calculator

Tips: Measure your area in square feet, determine desired depth in feet, and select appropriate density (100 lb/ft³ for sand, 110 lb/ft³ for typical gravel).

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for sand?
A: Dry sand is about 100 lb/ft³, wet sand about 120 lb/ft³.

Q2: How do I convert cubic feet to cubic yards?
A: Divide cubic feet by 27 (since 1 yd³ = 27 ft³).

Q3: How deep should I spread gravel for a driveway?
A: Typically 4-6 inches (0.33-0.5 feet) for residential driveways.

Q4: How do I measure irregular areas?
A: Break into rectangles, calculate each separately, then sum the volumes.

Q5: What's the difference between bank, loose and compacted volumes?
A: Material expands when excavated (loose) and compacts when placed. This calculator gives compacted volume.
