Project 10.5

This problem illustrates a numerical solution for the Instant Insanity puzzle. Let's associate numbers with the sides of the cubes of the Instant Insanity problem. Let White = 1;   Blue = 2;   Green = 3;   Red = 5




Now, the product across the top must be 30, and the product across the bottom must also be 30 (why?). It follows that a solution must have a product of 900 for the faces on the top and bottom. Consider the four cubes:
