Arrange some dice, stacking them on top of each other, so that the sum of dots on each vertical side of the rectangular parallelepiped is the same.
Of course that using an even number of dice the solution is simple.
What's the smallest odd number of dice that can be used?
What's the smallest sum that can be formed?
(In reply to re: solution (spoiler)
I have three non-regulation dice:
The top one shows 6,2,3,5; the middle 4,6,3,2, and the bottom one shows 2,4,6,5. The vertical sides are then:
6,4,2 = 12
2,6,4 = 12
3,3,6 = 12
5,2,5 = 12
