1. What is the Volume of Pentagonal Trapezohedron?

The volume of a pentagonal trapezohedron is the amount of three-dimensional space occupied by this geometric shape. It is calculated based on the total surface area using a specific mathematical formula.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{5}{12} \times (3+\sqrt{5}) \times \left( \sqrt{ \frac{TSA}{ \sqrt{ \frac{25}{2} \times (5+\sqrt{5}) } } } \right)^3 \]

Where:

\( V \) — Volume of Pentagonal Trapezohedron (m³)
\( TSA \) — Total Surface Area (m²)
\( \sqrt{} \) — Square root function

Explanation: The formula calculates the volume by first determining the appropriate scaling factor from the surface area, then applying the geometric properties specific to a pentagonal trapezohedron.

3. Importance of Volume Calculation

Details: Calculating the volume of geometric shapes is fundamental in various fields including architecture, engineering, and materials science. It helps in determining capacity, material requirements, and structural properties.

4. Using the Calculator

Tips: Enter the total surface area in square meters. The value must be positive and greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a pentagonal trapezohedron?
A: A pentagonal trapezohedron is a polyhedron with ten faces, each of which is a kite-shaped quadrilateral. It is the dual of the pentagonal antiprism.
