1. What is Volume of Square Tube?

Definition: This calculator computes the volume of a hollow square tube (square prism with a square hole).

Purpose: It helps engineers, architects, and metalworkers determine material volume for structural components.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of square tube (cubic units)
• \( S \) — Outer side length (units)
• \( s \) — Inner side length (units)
• \( L \) — Length of tube (units)

Explanation: The formula calculates the difference between the outer and inner cross-sectional areas, then multiplies by length.

3. Importance of Square Tube Volume Calculation

Details: Accurate volume calculation is essential for material estimation, weight calculation, and structural analysis.

4. Using the Calculator

Tips: Enter all dimensions in the same units. Outer dimension must be larger than inner dimension.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Any consistent unit (inches, cm, feet, meters). All inputs must use the same unit.

Q2: What if my inner dimension is larger than outer?
A: The calculator requires outer dimension > inner dimension for valid results.

Q3: Can I calculate weight with this?
A: Multiply volume by material density (e.g., steel = 0.283 lbs/cu in).

Q4: Does this work for rectangular tubes?
A: No, this is specifically for square tubes. Use different formula for rectangles.

Q5: How accurate is this calculation?
A: Perfectly accurate for ideal shapes. Real-world tubes may have slight variations.
