The term CUBE HAS TWELVE can be broken down into three crossword solutions: EDGES (5 letters), SIDES (5 letters), and STEPS (5 letters). A cube is a three-dimensional shape with six square faces, twelve edges, and eight vertices. The edges are the lines that connect two faces of the cube, while the sides are the flat surfaces of the cube. The steps refer to the corners of the cube, which are the points where three or more edges meet.
