The lateral area is the four rectangles that join the front to the back. I've shaded them red.

What do you get?

This rectangle just became the base of a regular prism, with a height of 6:

What is the lateral area?

What is the total surface area?

What is the volume?

What is the area of the largest rectangular side?
