1. What is a 3/4 River Rock Calculator?

Definition: This calculator estimates the volume of 3/4" river rock needed based on the area dimensions and desired depth.

Purpose: It helps landscapers and homeowners determine how much river rock is required for projects like landscaping, drainage, or decorative purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of river rock (cubic yards)
• \( L \) — Length (feet)
• \( W \) — Width (feet)
• \( D \) — Depth (feet)
• 27 — Cubic feet per cubic yard (conversion factor)

Explanation: The length, width, and depth are multiplied to get cubic feet, then divided by 27 to convert to cubic yards.

3. Importance of River Rock Volume Calculation

Details: Proper volume estimation ensures adequate coverage, proper drainage, and cost-effective material purchasing for landscaping projects.

4. Using the Calculator

Tips: Measure the area's length and width in feet, and enter the desired depth (typically 2-4 inches for decorative use). Convert inches to feet (e.g., 3 inches = 0.25 feet).

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard, so this conversion gives you the volume in standard landscaping measurement units.

Q2: What's a typical depth for river rock applications?
A: For decorative purposes: 2-4 inches (0.17-0.33 ft). For drainage: 4-6 inches (0.33-0.5 ft). For heavy use areas: 6-12 inches (0.5-1 ft).

Q3: How much does 3/4" river rock weigh?
A: Approximately 1.25-1.35 tons per cubic yard, depending on moisture content and rock type.

Q4: Should I account for compaction?
A: The calculator gives exact volume. For compaction, consider adding 10-15% to your total order.

Q5: How do I measure irregular areas?
A: Break into rectangular sections, calculate each separately, then sum the volumes.
