I WILL BE SUPER GRATEFUL IF ANYONE ANSWERS THIS WITH AN EXPLANATION: How many different pathways exist between A and C? (Never backtracking and only crossing at point B) The answer is 36, I'm not sure why though!

thanks so much! the only thing is though i'm looking for how many pathways are available from A to C, not A to B :) the answer is 36 but I'm not sure why the answer is what it is

3 ways at b in both cubes and then two different ways to get from a and two ways to get to c.

starting at A, you have 3 routes to take to reach the other corner

for each of those 3 routes, u have 2 routes to take again to reach B : 3 x 2 = 6 ways to reach till B.
