5-10.

Visualize a sofa or couch you know well. If you cut it right down the middle vertically, what will the cross-section look like? Make a sketch, but do not try to verify your work!

Answers will vary, but it should have an “L” shape to it. In the middle there would probably not be any armrests to cut through.
