1. What is Liquid Volume of a Rectangle Calculator?

Definition: This calculator estimates the volume of liquid a rectangular container can hold, measured in gallons.

Purpose: It helps determine how much liquid (water, chemicals, etc.) a rectangular tank, box, or container can hold.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{gal} \) — Volume in gallons
• \( L \) — Length of container (inches)
• \( W \) — Width of container (inches)
• \( H \) — Height of container (inches)

Explanation: The formula calculates cubic inches (L×W×H) then converts to gallons (1 gallon = 231 cubic inches).

3. Importance of Liquid Volume Calculation

Details: Accurate volume calculations are essential for proper container sizing, chemical dosing, and liquid storage planning.

4. Using the Calculator

Tips: Measure the interior dimensions of your container in inches. Enter all three dimensions (length, width, height) as positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: 231 cubic inches equals 1 US liquid gallon, which is the standard conversion factor.

Q2: Does this work for any liquid?
A: Yes, it calculates volume. For weight, you'd need to multiply by the liquid's specific gravity.

Q3: What if my container isn't full?
A: Use the actual liquid height for H to calculate partial volume.

Q4: Can I use feet instead of inches?
A: Convert feet to inches first (1 foot = 12 inches) for accurate results.

Q5: How precise is this calculation?
A: It's mathematically precise for perfect rectangles. Real containers may have slight variations.
