Cube Corners
A cube has six faces (sides) and eight vertices (corners). Arrange the numbers 1 through 8, placing one number at each corner, such that the sum of the four corners of each side is the same for all six sides.
Answer
The sum of the four corners of each side is 18. The four numbers on one side are 8 (upper left), 1 (upper right), 6 (lower right), and 3 (lower left). On the opposite side, directly behind those four numbers, are 2, 7, 4, and 5. There are seemingly other arrangements, but they are all due to the orientation of the cube.Hide Answer Show Answer
