Claim:
1. An origami sheet for making a regular hexahedron box, comprising: first to fourth main outer wall sections connected successively along a longitudinal central area to be foldable with regard to one another; first to fourth wing sections connected to each longitudinal side of the first to fourth main outer wall sections to be foldable, respectively, wherein the first and second wing sections and the third and fourth wing sections are connected to be foldable with regard to each other, and the second and third wing sections are separated from each other by interposed incision lines; and a reinforcement extension that extends along a longitudinal direction from the longitudinal edges of the first wing sections and the first main outer wall section, wherein the reinforcement extension comprises a first reinforcement extension comprising a first front reinforcement section, which is connected to be foldable in the longitudinal direction from the first main outer wall section, and first wing reinforcement extensions connected to both transverse sides of the first front reinforcement section to be foldable, respectively, wherein the reinforcement extension comprises a second reinforcement extension comprising a second front reinforcement section, which is connected to be foldable in the longitudinal direction with regard to the first reinforcement extension and second wing reinforcement extensions connected to both transverse sides of the second front reinforcement section to be foldable, respectively, and the second wing reinforcement sections comprise inner folding lines that are formed diagonally from vertices, at which a longitudinal end of the sheet meets folding lines of the second front reinforcement section.
