1. What is Surface to Volume Ratio of Snub Cube?

The Surface to Volume Ratio of a Snub Cube is a geometric measurement that compares the total surface area of this Archimedean solid to its volume. It's an important parameter in materials science, chemistry, and physics for understanding properties like reactivity, heat transfer, and diffusion rates.

2. How Does the Calculator Work?

The calculator uses the specialized formula:

\[ RA/V = \frac{2 \times (3 + 4\sqrt{3})}{\left(\frac{3\sqrt{[Tribonacci_C]-1} + 4\sqrt{[Tribonacci_C]+1}}{3\sqrt{2-[Tribonacci_C]}}\right) \times \frac{r_m}{\sqrt{\frac{1}{4(2-[Tribonacci_C])}}}} \]

Where:

\( [Tribonacci_C] \) — Tribonacci constant (≈1.839286755214161)
\( r_m \) — Midsphere radius of the Snub Cube
All square root and arithmetic operations follow standard mathematical rules
