Are you a professional problem solver? If so, we invite you to submit your “Ponder This” solution for this month’s challenge. Ponder This is IBM Research’s monthly brain-twister where you can match wits with some of the best minds at IBM.
Ponder This Challenge:
If you juxtapose a regular hexagon to an equilateral triangle (where all the edges of both polygons share the same unit length) on a common edge – you get a polygon with five vertices; five edges; and one face.
If you juxtapose a four-dimensional pyramid whose base is a right triangular prism to a four-dimensional pyramid whose base is a tetrahedron (again: all the edges of both polychora shares the same unit length) on a common tetrahedron – how many vertices, edges, faces, and cells would the resulting polychoron have?
IBM Research will post the names of those who submit a correct, original solution to their website! If you don’t want your name posted then please include such a statement in your submission. Send your submission to the webmaster.
