    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)
    Great, fast and reliable
