The weirdest question was "If you have a 3x3 Rubik's cube and removed one row and one column how many cubes are left?" The kid that asked me the question looked to be about 19yo.

The answer could also conceivably be 8 (i.e. a 2x2x2 cube) if you're taking out a row and a column all the way through the cube. The question as phrased is not very clear.

Yah I did coursetake's course too and they had such questions covered. Very weird to see these questions pop up in Uber. Going into my test soon.

3x3 Rubik's Cube yields you 27 individual pieces. If you remove 1 row and 1 column that intersects, you remove 5 altogether to get you 22 pieces If you remove 1 row and 1 column that DOES NOT intersect, you remove 6 altogether to get you 21 pieces
