Purpose of use
I had a math project that required me to find the volume and surface area of a polyhedron and this was super helpful since I don't know the formulas. Thanks :D

Purpose of use
Amazing calculator for my math project on regular and Archimedean solids, and helped me learn more about math (I knew face, vertex, edge count but not volume)
