The correct response is:
The net of the fish tank with no lid has four rectangular faces, two pairs of congruent rectangles, and the net of the fish tank with its lid has six rectangular faces, three pairs of congruent rectangles.
The fish tank with no lid consists of four rectangle faces corresponding to the sides and the bottom. Conversely, the fish tank with a lid has six rectangular faces: four sides, a bottom, and a top (the lid).
