Best ResponseYou've already chosen the best response.0Well, I suppose you know how to find the area of a rectangle. It's a lot like that, but for 6 rectangles! I'll start you off. 3 in times 11 in = 33. Since it's the same on the other side that's 66 square inches. Can you do the rest? (you only need to do two more, just multiply them by two sine the opposite side will always be the same.) Once you're done you can add them up.
