1. What is a Gravel Fill Calculator?

Definition: This calculator estimates the volume of gravel needed based on the length, width, and depth of the area to be filled.

Purpose: It helps determine how much gravel is required for projects like driveways, walkways, or foundation bases.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The calculator multiplies the three dimensions to get cubic feet, then converts to cubic yards.

3. Importance of Gravel Volume Calculation

Details: Accurate gravel estimation prevents over-ordering (saving money) or under-ordering (preventing project delays).

4. Using the Calculator

Tips: Measure the area carefully in feet. For depth, consider both the desired gravel depth and any compaction that will occur.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard, so we convert from cubic feet to cubic yards.

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

Q3: What depth should I use?
A: Typical depths are 2-4 inches for walkways (convert to feet: 2" = 0.167'), 4-6" for driveways.

Q4: Should I add extra for compaction?
A: Yes, consider adding 10-20% more volume if the gravel will be compacted.

Q5: How many tons is this?
A: Multiply cubic yards by 1.4 (average gravel density) to estimate tons needed.
