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 Tetrahedron given Face Area?
Insphere Radius of Tetrahedron given Face Area calculator uses Insphere Radius of Tetrahedron = sqrt((4*Face Area of Tetrahedron)/sqrt(3))/(2*sqrt(6)) to calculate the Insphere Radius of Tetrahedron, Insphere Radius of Tetrahedron given Face Area formula is defined as the radius of the sphere that is contained by the Tetrahedron in such a way that all the faces just touching the sphere, and calculated using the face area of the Tetrahedron. Insphere Radius of Tetrahedron is denoted by ri symbol.
