Formula to Calculate Yards of Gravel Available

Gravel Volume Formula:

\[ V = \frac{L \times W \times D}{27} \]

Gravel Volume (cu yd):

1. What is the Gravel Volume Calculator?

Definition: This calculator estimates the volume of gravel in cubic yards based on the area's length, width, and depth.

Purpose: It helps determine how much gravel is needed for landscaping, construction, or other projects requiring gravel coverage.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{L \times W \times D}{27} \]

Where:

\( V \) — Volume of gravel (cubic yards)
\( L \) — Length of area (feet)
\( W \) — Width of area (feet)
\( D \) — Depth of gravel (inches, converted to feet)
27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator multiplies length × width × depth (converted to feet), then divides by 27 to convert cubic feet to cubic yards.

3. Importance of Gravel Volume Calculation

Details: Accurate gravel volume estimation ensures proper material ordering, cost control, and project planning for driveways, pathways, or foundations.

4. Using the Calculator

Tips: Measure the area's length and width in feet, and desired gravel depth in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard, so this converts the volume from cubic feet to cubic yards.

Q2: How do I measure irregular areas?
A: For irregular shapes, divide into rectangular sections, calculate each separately, then sum the volumes.

Q3: What's a typical gravel depth?
A: For driveways: 4-6 inches, for walkways: 2-3 inches, for drainage: 6-12 inches.

Q4: How much does a cubic yard of gravel cover?
A: At 3-inch depth: ~100 sq ft, at 6-inch depth: ~50 sq ft.

Q5: Does this include compaction factor?
A: No, consider adding 10-20% more gravel to account for compaction over time.
