Calculate Cubic Yards from Perimeter

Volume Formula:

\[ V = \frac{P \times D}{4 \times 27} \]

Volume (cubic yards):

1. What is Cubic Yards from Perimeter Calculator?

Definition: This calculator estimates the volume in cubic yards based on perimeter measurements and depth, assuming a square or rectangular area.

Purpose: It helps construction professionals and landscapers quickly determine material quantities needed for perimeter-based projects.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{P \times D}{4 \times 27} \]

Where:

\( V \) — Volume (cubic yards)
\( P \) — Perimeter (feet)
\( D \) — Depth (feet)
4 — Factor to convert perimeter to side length (assuming square)
27 — Cubic feet per cubic yard conversion factor

Explanation: The perimeter is divided by 4 to estimate side length (assuming a square area), multiplied by depth for cubic feet, then divided by 27 to convert to cubic yards.

3. Importance of Volume Calculation

Details: Accurate volume estimation ensures proper material ordering for projects like footings, trenches, or perimeter drainage systems.

4. Using the Calculator

Tips: Enter the perimeter in feet and depth in feet. The calculator assumes a square shape. For rectangles, use (2*length + 2*width) as perimeter.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 4 in the formula?
A: For a square, perimeter = 4 × side length, so dividing by 4 gives us the length of one side.

Q2: How accurate is this for non-square areas?
A: Less accurate. For rectangles, calculate perimeter as (2×length + 2×width). For circles, use different formulas.

Q3: What's the 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet).

Q4: Can I use this for concrete calculations?
A: Yes, but remember this calculates volume, not weight. Concrete weighs about 1.35 tons per cubic yard.

Q5: Should I add extra for compaction or waste?
A: Yes, consider adding 5-15% to the calculated volume depending on material and project requirements.
