Chapter 13.2, Problem 18P

Tim needs a sturdy cardboard box that is 3 ft tall by 2 ft long by 1 ftwide. He wants to make the box out of a large piece of cardboard that he will cut, fold, and tape. The box must close up completely, so it needs a top and a bottom. Show Tim how to make such a box out of one rectangular piece of cardboard: Tell Tim what size cardboard he’ll need to get (how wide, how long) and explain or show how he should cut, fold, and tape the cardboard to make the box. Be sure to specify exact lengths of any cuts Tim will need to make. Include pictures where appropriate. Your instructions and box should be practical; Tim should be able to actually make and use the box. You might want to make a scale model for your box out of paper. Note: Many boxes have flaps around all 4 sides that one can fold down and interlock to make the top and bottom of the box. You can make this kind of top and bottom, or something else if you prefer, but make sure it will make a sturdy box that closes completely.
