1. What is the Total Surface Area of Elongated Pentagonal Pyramid?

The Total Surface Area of an Elongated Pentagonal Pyramid is the sum of the areas of all its faces, including the pentagonal base, triangular faces, and rectangular faces resulting from the elongation. It represents the complete exterior surface area of the 3D shape.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = \left( \frac{\sqrt{25 + 10\sqrt{5}}}{4} + \frac{5\sqrt{3}}{4} + 5 \right) \times \left( \frac{h}{\sqrt{\frac{5 - \sqrt{5}}{10}} + 1} \right)^2 \]

Where:

\( TSA \) — Total Surface Area of Elongated Pentagonal Pyramid
\( h \) — Height of Elongated Pentagonal Pyramid
\( \sqrt{} \) — Square root function

Explanation: The formula combines geometric constants related to pentagonal geometry with a scaling factor based on the pyramid's height to calculate the total surface area.

3. Importance of Surface Area Calculation

Details: Calculating surface area is crucial for various applications including material estimation, structural analysis, heat transfer calculations, and architectural design of pyramidal structures.
