Hi all, I'm looking for an app for Mac OS or iOS that will calculate the volume of a polyhedron with irregular sides. Basically the solid would look similar to a prism with 6 sides but the edges are not parallel. So each edge would have a different length. I'm not terribly great at math so a simple utility where I would input the length of each of the 12 edges and then output the volume would be great. I do a lot of these. Thanks
