1. What is a Volume of a Solid Calculator?

Definition: This calculator computes the volume of various three-dimensional shapes based on their dimensional measurements.

Purpose: It helps students, engineers, and professionals quickly determine the space occupied by different geometric solids.

2. How Does the Calculator Work?

The calculator uses shape-specific formulas:

Where:

• \( V \) — Volume (cubic units)
• \( L \) — Length (rectangular)
• \( W \) — Width (rectangular)
• \( H \) — Height (rectangular)
• \( r \) — Radius (cylindrical)
• \( h \) — Height (cylindrical)

Explanation: The calculator applies the appropriate geometric formula based on the selected shape and provided dimensions.

3. Importance of Volume Calculation

Details: Accurate volume calculations are essential in construction, manufacturing, shipping, and scientific research to determine capacity, material requirements, and space utilization.

4. Using the Calculator

Tips: Select the shape, enter all required dimensions (must be > 0), and click Calculate. All measurements should be in the same units.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Use any consistent units (inches, feet, meters, etc.), but all inputs must be in the same units.

Q2: Can I calculate volume for other shapes?
A: Currently supports rectangular and cylindrical shapes. More shapes may be added in future updates.

Q3: How precise are the calculations?
A: Results are precise to 3 decimal places. For π (pi), we use PHP's built-in pi() function.

Q4: What if I get zero or negative results?
A: All dimensions must be positive numbers. The calculator validates inputs to prevent invalid calculations.

Q5: Can I calculate volume in gallons or liters?
A: First calculate in cubic units, then convert using appropriate conversion factors (not included here).
