1. What is the Gravel and Sand Calculator?

This calculator helps determine the volume and weight of gravel or sand needed for landscaping projects based on area, depth, and material density.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( Area \) — Surface area to be covered (m²)
• \( Depth \) — Depth of material layer (m)
• \( Density \) — Material density (kg/m³)

Explanation: The calculation first determines the volume of material needed, then calculates the weight based on the material's density.

3. Importance of Accurate Calculations

Details: Accurate volume and weight calculations are crucial for proper material ordering, cost estimation, and ensuring structural integrity in landscaping projects.

4. Using the Calculator

Tips: Enter the area in square meters, depth in meters, and material density in kg/m³. Typical densities: gravel ~1500-1700 kg/m³, sand ~1600 kg/m³ (dry).

5. Frequently Asked Questions (FAQ)

Q1: How do I measure the area?
A: For rectangular areas, multiply length by width. For irregular shapes, divide into regular sections and sum their areas.

Q2: What depth should I use?
A: Typical depths: 5-10cm for decorative gravel, 10-15cm for driveways, 2-5cm for sand under pavers.

Q3: Where can I find material density?
A: Suppliers typically provide density information. Average values: gravel 1500 kg/m³, sand 1600 kg/m³.

Q4: How do I convert to tons?
A: Divide the weight in kg by 1000 to get metric tons (1 ton = 1000 kg).

Q5: Should I add extra material?
A: It's recommended to add 5-10% extra to account for compaction and spillage during transport.
