    Hello mocogi. Welcome to the Forum. Normally to receive help in this forum you are expected to show what thought or work you have applied to your problem.

    I suppose you mean "squares" instead of cubes. I will give you a little hint. Considering each move to the right or up as a "step", how many total steps do you need? How many ways can you choose which steps to use for the up moves?
