This net is folded into a cube, which is then placed with J on the table and K facing you. Which letter is on the right-hand face?

From the net: J is opposite L, K is opposite G and H is opposite M, so with J below and K in front, L is on top, G at the back, and H and M are the two side faces. Lay the net printed side down with J as the base and K towards you: K folds up as the front, L folds over it to become the top, and M, hanging off the end of L, folds down on your right. H folds up on the left.
