This example demonstrates how to construct a rectangular prism with maximum volume given a fixed perimeter by adjusting the length-width ratio. Key math concepts include volume calculation, function optimization, derivative application, and extreme value determination. GeoGebra commands and objects used in the construction are Intersect, Textfield, Segment, and Max, as summarized. It is suitable for high school and above students to understand the application of calculus in geometric optimization problems, and can also serve as an introduction to distribution analysis in probability & statistics.
