Problem
Each corner of a rectangular prism is cut off. Two (of the eight) cuts are shown. How many edges does the new figure have?
Assume that the planes cutting the prism do not intersect anywhere in or on the prism.
Solution
In addition to the original edges, each original vertex contributes new edges.
There are original vertices, so there are edges in the new figure .
