Students first make physical models using paper and scissors to get a grasp of the problem and to determine how to set it up. They then use the CAS of the TI-89 and calculus to determine the dimensions of the box which gives the maximum volume.
Before the Activity
Students should have access to TI-89/TI-89 Titanium and TI-92 Plus/Voyage.
During the Activity
