1. What is 2B Stone?

2B stone is clean crushed gravel with a size range of 1/2" to 3/4". It's commonly used for drainage applications, driveways, and as a base material for patios and walkways.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( length \) — Length in feet
• \( width \) — Width in feet
• \( depth \) — Depth in inches
• \( density \) — Material density in tons per cubic yard (typically 1.35 for 2B stone)

Explanation: The formula first converts all measurements to yards, calculates cubic yards, then multiplies by density to get tons.

3. Importance of Accurate Calculation

Details: Accurate tonnage 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 carefully in feet. Typical depth for driveways is 4-6 inches. The default density of 1.35 tons/cu yd is standard for 2B stone.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between 2B and 2A stone?
A: 2A contains stone dust which helps with compaction, while 2B is cleaner and better for drainage.

Q2: How much does 2B stone typically cost?
A: Prices vary by region but typically range from $25-$50 per ton plus delivery.

Q3: How do I measure irregular areas?
A: Break the area into rectangles, calculate each separately, then sum the totals.

Q4: How much will a ton of 2B stone cover?
A: At 2" depth, about 100 sq ft; at 4" depth, about 50 sq ft.

Q5: Should I order extra material?
A: It's recommended to order 10-15% extra to account for compaction and uneven surfaces.
