You are drawing 2D, and try to understand 3D w/o spatial visualization. My advice is to get paper and scissors and built a set of 8 cubes. Use the cubes for control volume sector, and join them....

In a 2D case with only quad elements, a control volume shares 4 quad elements. Within an element, the faces of the control volume starts at the midpoint of the edges of the element towards the center...
