Question

What is the surface area of the composite figure?

Answer 1

Try drawing out the figure as if all the sides could be flattened out. It doesn't have to be perfect, just so that you can see all the surfaces. Remember, you're finding the surface area not the volume!

Answer 2

Try thinking about what you need to draw by drawing all the tops, all the bottoms, left, right, front, and back sides to make sure you didn't forget anything.

Answer 3

Split it up ....
