1. What is Surface to Volume Ratio of Icosahedron?

The Surface to Volume Ratio of an Icosahedron is a geometric measurement that compares the total surface area to the volume of this 20-faced polyhedron. It's an important parameter in various scientific and engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ RA/V = \frac{12\sqrt{3}}{(3+\sqrt{5})\sqrt{\frac{4 \times AFace}{\sqrt{3}}}} \]

Where:

\( RA/V \) — Surface to Volume Ratio (1/m)
\( AFace \) — Face Area of Icosahedron (m²)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)
\( \sqrt{5} \) — Square root of 5 (approximately 2.236)

Explanation: This formula calculates the surface to volume ratio based on the area of one face of the icosahedron, utilizing geometric properties of this regular polyhedron.

3. Importance of Surface to Volume Ratio

Details: The surface to volume ratio is crucial in materials science, chemistry, and physics as it affects properties like heat transfer, chemical reactivity, and mechanical strength. For icosahedral structures, this ratio is particularly important in nanotechnology and molecular studies.

4. Using the Calculator

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