E will be on top, C will be to the right.
Work Step by Step
Looking at problem 1, when C is in the front E is on top and D is to the right. In the version shown here, the cube has been rotated so that B is now in the front. We know the cube has not been flipped because the letter B is still right side up, so E is still on top. C is to the right of B in the net, so it is still to the right of B on the cube.
