Max Box

This resource is an interactive excel program which provides dynamic drawings and graphs related to the classic maximum volume of a box problem. There are two versions of the problem, one starting with a square base and the other with a rectangular base.

Each interactive sheet shows the height, width and length of the box as the height changes. In addition to the dynamic drawings the program shows a graph of the volume of the box against the height. Tangents can be shown on the graphs so that the student can see approximately where the maximum point is.

This program was designed to be viewed on a screen with a resolution of 1024 x 768. Users may have to adjust the resolution of their screen for the pages to display as was originally intended. The program uses macros which need to be enabled on a machine.
