A snub dodecahedron is a non-convex polyhedron that is classified under the Archimedean solids. It is constructed by altering a dodecahedron through a process called "snubbing," which involves truncating its vertices and edges.
The snub dodecahedron holds significance in geometry due to its unique geometric properties and symmetrical structure. It serves as an example of the fascinating interplay between symmetry, regularity, and complexity in three-dimensional space. Mathematicians and researchers often study the snub dodecahedron to explore concepts such as polyhedral symmetry, polyhedral combinatorics, and the geometric relationships between its faces, edges, and vertices.
The Snub Dodecahedron Calculator is designed to compute various geometric properties based on the input of the edge length (a) of a snub dodecahedron. Its features include:

Users can input the edge length (a) and specify the decimal precision for rounding results. The calculator ensures accurate computations and provides instant feedback on the geometric characteristics of the snub dodecahedron.
The edge length (a) refers to the length of each edge of the snub dodecahedron, which is a crucial parameter in determining its geometric properties.
Surface Area (A) represents the total area of all the faces of the snub dodecahedron. It is calculated based on the edge length (a) using specific geometric formulas.
Volume (V) denotes the amount of space enclosed within the snub dodecahedron. It is computed using the edge length (a) and involves cubic calculations with mathematical constants.
Circumsphere Radius (rc) refers to the radius of the circumscribed sphere that touches all vertices of the snub dodecahedron. It is derived using the edge length (a) and geometric relationships.
Midsphere Radius (rm) is the radius of the inscribed sphere that is tangent to all faces of the snub dodecahedron. Its calculation involves the edge length (a) and specific geometric formulas.
Surface-to-Volume Ratio (A/V) is a dimensionless quantity that indicates how much surface area (A) exists per unit volume (V) of the snub dodecahedron. It is computed using the ratios of their respective properties.
Surface Area (A) = a2 * (20√3 + 3√(25 + 10√5))
Volume (V) = a3 * [12ξ2(3φ + 1) - ξ(36φ + 7) - (53φ + 6)] / [6(√(3 - ξ2))3]
Circumsphere Radius (rc) = a * φ * √(ξ(ξ + φ) + (3 - φ)) / 2
Midsphere Radius (rm) = a * φ * √(ξ(ξ + φ) + 1) / 2
Surface-to-Volume Ratio (A/V) = (20√3 + 3√(25 + 10√5)) * [6(√(3 - ξ2))3] / [a * (12ξ2(3φ + 1) - ξ(36φ + 7) - (53φ + 6))]
