You can see three sides of each of two dice, and notice that the total number of pips showing is a perfect cube.
What are the numbers of pips on each face that you see?
If you want to get really technical, nowhere in this question does it mention a six-sided die, nor does it mention that the numbers are 1 to 6.
There are 5 solutions if you assume the above (1 being the solution posted where you can't see the back of any numbers). Can you find them?
