What are Platonic Solids?
In three-dimensional space, a Platonic solid is a regular, convex polyhedron. It is constructed by congruent (identical in shape and size), regular (all angles equal and all sides equal), polygonal faces with the same number of faces meeting at each vertex. Five solids who meet this criteria are Tetrahedron {3,3} , Cube {4,3} , Octahedron {3,4} , Dodecahedron {5,3} , Icosahedron {3,5} ; where in {p, q}, p represents the number of edges in a face and q represents the number of edges meeting at a vertex; {p, q} is the Schläfli symbol.
How to Calculate Insphere Radius of Icosahedron?
Insphere Radius of Icosahedron calculator uses Insphere Radius of Icosahedron = (sqrt(3)*(3+sqrt(5)))/12*Edge Length of Icosahedron to calculate the Insphere Radius of Icosahedron, Insphere Radius of Icosahedron formula is defined as the radius of the sphere that is contained by the Icosahedron in such a way that all the faces just touching the sphere. Insphere Radius of Icosahedron is denoted by ri symbol.
