If they are perpendicular, there is zero push. If they are parallel, there is maximum push. The dot product gives a single number, a scalar. The cross product is a way to find the "area" spanned by two vectors. In this case, you want them to be perpendicular (to make the largest polygon). If they are parallel, there is no "area" between them. The cross product gives another vector, which is perpendicular to the input vectors.
