1. What is a Rectangular Volume Calculator?

Definition: This calculator estimates the volume of a rectangular space in gallons based on its dimensions 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

Explanation: The formula multiplies the three dimensions to get cubic inches, then divides by 231 (cubic inches per gallon) to convert to gallons.

3. Importance of Volume Calculation

Details: Accurate volume calculations are essential for liquid storage, aquarium sizing, chemical mixing, and industrial tank design.

4. Using the Calculator

Tips: Enter all dimensions in inches. The calculator will automatically convert to gallons. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: There are exactly 231 cubic inches in one US liquid gallon, which is the standard conversion factor.

Q2: Can I use different units?
A: This calculator requires inches. For other units, convert to inches first or use a different calculator.

Q3: Does this work for irregular shapes?
A: No, this only calculates volume for perfect rectangular prisms. Use different formulas for other shapes.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, but actual capacity may vary due to container thickness or internal features.

Q5: What's a practical application?
A: Useful for determining how much water a fish tank holds or how much liquid a rectangular container can store.
