1. What is Volume of a 3D Shape?

Definition: Volume is the amount of space occupied by a three-dimensional object.

Purpose: Calculating volume is essential in construction, manufacturing, packaging, and many scientific applications.

2. How Does the Calculator Work?

The calculator uses different formulas based on the selected shape:

\[ V = L \times W \times H \text{ (rectangular)} \] \[ V = \pi \times r^2 \times h \text{ (cylindrical)} \]

Where:

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

3. Importance of Volume Calculation

Details: Accurate volume calculations are crucial for material estimation, capacity planning, and structural design.

4. Using the Calculator

Tips:

Select the shape (rectangular or cylindrical)
Enter the required dimensions
All values must be positive numbers
The calculator will automatically show the appropriate input fields

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: You can use any consistent units (meters, feet, inches, etc.). The result will be in cubic units of your input.

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 calculated to 3 decimal places for precision.

Q4: What if my shape is irregular?
A: For irregular shapes, you may need to break them down into regular components or use more advanced methods.

Q5: Does this account for material thickness?
A: No, this calculates total volume. For hollow objects, you would need to subtract the inner volume.
