what is the total number of edges of an octagonal prism?
Total number of edges of an octagonal prism will be #24#. An octagon is a polynomial with eight sides. An octagonal prism will have two octagonal faces i.e. a total of #8xx2=16# sides as edges. And additionally all eight corners of one octagon will be connected to eight corners of other octagon, forming #8# edges. Hence total number of edges of an octagonal prism will be #16+8=24#.
