1. What is the Total Surface Area of Pentagonal Cupola?

The Total Surface Area of a Pentagonal Cupola is the total amount of 2D space occupied by all the faces of this geometric solid. A pentagonal cupola is a polyhedron formed by attaching a pentagon and a decagon with alternating triangles and rectangles.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = \frac{1}{4} \left(20 + 5\sqrt{3} + \sqrt{5(145 + 62\sqrt{5})}\right) \left( \frac{V}{\frac{1}{6}(5 + 4\sqrt{5})} \right)^{\frac{2}{3}} \]

Where:

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

Explanation: This formula calculates the total surface area based on the given volume of the pentagonal cupola, using mathematical constants and geometric relationships specific to this shape.

3. Importance of Surface Area Calculation

Details: Calculating the total surface area is important for various applications including material estimation, structural analysis, and geometric modeling of pentagonal cupola structures.

4. Using the Calculator

Tips: Enter the volume of the pentagonal cupola in cubic meters. The value must be positive and valid for accurate calculation of the total surface area.
