Can someone describe the steps to make a paper cube from a sheet of cardbord with squares (3x5) - the second and forth squares from the second row are removed. The sheet looks like this (black boxes are cut):

Instructions:
Dashed lines are valley folds (up towards you)
Dotted lines are mountain folds (away from you)

Well, it took a bit of cutting, folding, and cursing, but I think Ben's solution actually works. Heck of a lot of waste, though, so since you didn't specify what we could and couldn't do, how about this? Cut all but one square in half along its diagonal, giving you 24 right triangles. Collect these into six groups of four and glue each group together so that they form six squares where the boundaries of the squares are the diagonals of the triangles. Now you have the left, right, front, back, top, and bottom sides of a cube, each having edge length $\sqrt{2}$. Throw away the square you didn't cut at the start, or cut it into six rectangles and glue one on each face for decoration.
