Best ResponseYou've already chosen the best response.0You should draw a rectangular prism and put in the length, width and height. Can you do this first?

Best ResponseYou've already chosen the best response.0It's just going to be the sum of the rectangles that make up that surface. That's why I got you to draw it, so you don't lose track.

Best ResponseYou've already chosen the best response.0The face closest to you in my pic. has an area of 10 x 11 = 110 inches squared. But there's another one of these on the other side. So you so far have two faces whose area you know. Now look at the side of prism. It has dimensions 9 x 10 = 90 inches squared. But again, you have two faces this size (the one on the other side too). So now you know the area of four of the six faces. Lastly, look at the face on top. It will have dimensions 11 x 9 = 99 inches squared. But again, there's another face with this area on the bottom. You now know the area of each of the faces of the prism. All you have to do is add them up.
