A rectangle is described as a quadrilateral with four 90 degree angles or two sets of parallel lines. A square is described as a quadrilateral with equal sides and two sets of parallel lines. All faces of a cube is are rectangles.
In any cube, you can sort the edges into three sets, with 4 edges in each set. All four edges in a set are parallel to each other, and none of the edges in one set is parallel to any of the edges in any other set.
