1. What is a Volume Calculator for Rectangles?

Definition: This calculator estimates the volume of a rectangular space in gallons based on its length, width, and height in inches.

Purpose: It helps determine liquid capacity of rectangular containers, tanks, or spaces for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{gal} \) — Volume in gallons
• \( L \) — Length in inches
• \( W \) — Width in inches
• \( H \) — Height in inches
• 231 — Cubic inches per gallon (conversion factor)

Explanation: The product of length, width and height gives cubic inches, which is converted to gallons by dividing by 231.

3. Importance of Volume Calculation

Details: Accurate volume calculation is essential for liquid storage, aquarium sizing, tank capacity planning, and chemical mixing.

4. Using the Calculator

Tips: Enter the length, width and height in inches. All values must be > 0. The result shows the volume in US gallons.

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use this for irregular shapes?
A: No, this only works for perfect rectangular shapes. For irregular shapes, use different methods.

Q3: What if my measurements are in feet?
A: Convert feet to inches first (1 foot = 12 inches) before using the calculator.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect rectangles. Real-world containers may vary slightly.

Q5: Does this work for imperial gallons?
A: No, this uses US gallons (231 cu in). Imperial gallons use 277.42 cubic inches.
