1. What is a Volume Calculator?

Definition: This calculator computes the volume of different shapes including rectangular prisms and cylinders.

Purpose: It helps in various fields like construction, engineering, and education to determine the space occupied by objects.

2. How Does the Calculator Work?

The calculator uses different formulas based on shape:

Where:

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

3. Importance of Volume Calculation

Details: Volume calculations are essential for material estimation, container capacity, space planning, and many scientific applications.

4. Using the Calculator

Tips:

1. Select the shape (rectangular or cylindrical)
2. Enter the required dimensions
3. All values must be positive numbers
4. The calculator works with any consistent unit of measurement

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Use any consistent unit (inches, feet, meters, etc.) as long as all dimensions use the same unit.

Q2: Can I calculate volume for other shapes?
A: Currently this calculator supports rectangular and cylindrical shapes only.

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

Q4: Why does my cylindrical calculation seem large?
A: Remember volume increases with the square of the radius - doubling the radius quadruples the volume.

Q5: Can I calculate in metric and imperial units?
A: Yes, as long as all dimensions use the same unit system.
