Dice can also be (regular) dodecahedrons, which consist of twelve equilateral pentagons. Their sides are then labeled with the numbers from 1 to 12, whose opposite sides add up to 13.
How many such dodecahedral cubes are possible under these conditions?
Thats a Question my 12 grade teacher gave me for homework but i cant seem to find an answer

  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:

  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Unless you're talking about, like, cubed numbers somehow relating to a dodecahedron, "dodecahedral cube" makes as much sense as "square circle".

Probably typed cubes instead of dice. How do we proceed tho

probably rotations, probably not reflections

#

so
you can put side 1 on the top
then, there are 5 other symmetrical opposite-side pairs surrounding
fill those with the rest of the number pairs, each has 2 options (which number is on the top row) and ensure to divide by 5 so that you don't quintuple-count the patterns

then we determine that at a later point

In general, it's very poor practice to assume someone meant something other than what they said in math, and very poor practice to get into the habit of not saying precisely what you mean.
