1 of each 2^x coins is basically binary right? So only one way of making any number up (its binary representation!)

37:30 You could use the '3D' interpretation, it is easy to see that if you moved the cube to see each face front on, one would be fully grey, the other fully blue, and the top one fully orange, so we have 30*2 for each. There is no way to look at the cube up-down and see a grey or blue tile. Not sure how to make it more rigorous tho
