## Main Question or Discussion Point

I'm looking for an easy way to get the surface area of an arbitrary shaped 3D object. Getting the volume is easy by water displacement. What about area? Any neat tricks? We know different shapes can have the same volume and thus different surface areas so it's not a trivial problem. The purpose is for estimating surface area of 3D printed plastic parts which will undergo copper plating. Thanks!
