How many faces?

How many edges?

How many vertices?

**MathMate**, Sunday, June 12, 2011 at 8:11amA cuboid is like a box, so it has f = 6 faces, v = 8 vertices (corners) and e = 12 edges.

You can verify the answer by putting the numbers in the Euler formula:

v + f = e + 2

or

8 + 6 = 12 + 2

14 = 14 (so the answers are probably correct)

Here's a link to the shape of a triangular prism, from which you can deduce the number of faces, edges, and vertices.
