1. What is Volume of Three Dimensional Figures?

Definition: Volume is the amount of space occupied by a three-dimensional object, measured in cubic units.

Purpose: This worksheet helps students and professionals calculate volumes of common 3D shapes for educational and practical applications.

2. How Does the Calculator Work?

The calculator uses different formulas based on the selected shape:

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

Where:

For rectangular prisms: L (length), W (width), H (height)
For cylinders: r (radius), h (height)
V is always in cubic units (units³)

3. Importance of Volume Calculation

Applications: Volume calculations are essential in construction, manufacturing, science experiments, packaging, and many real-world scenarios.

4. Using the Worksheet

Instructions:

Select the shape (rectangular prism or cylinder)
Enter the required dimensions
All values must be positive numbers
Click Calculate to get the volume

5. Frequently Asked Questions (FAQ)

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

Q2: How precise should my measurements be?
A: For educational purposes, two decimal places are usually sufficient. For real-world applications, match your measurement precision to the requirements.

Q3: Can I calculate volume for other shapes?
A: This worksheet currently supports rectangular prisms and cylinders. Other shapes may be added in future versions.

Q4: Why is π (pi) used in the cylinder formula?
A: Pi relates the diameter of a circle to its circumference and is essential for circular area calculations.

Q5: How do I measure radius vs diameter?
A: Radius is half the diameter. Make sure to use radius in the calculator, not diameter.
