How to model and analyse an open box</h3>
a) The volume of the box (), in cubic centimeters, is equal to the area of the base (), in square centimeters, multiplied by the height of the box (), in centimeters. The area of the surface is the product of the width () and length (l), both in centimeters:
(1)
The volume of the container is cubic centimeters.
b) We need to apply first derivative analysis and second derivative analysis to determine the dimensions of the <em>maximum</em> squares to be cut:
<h3>FDT</h3>
<h3>SDT</h3>
Since , the <em>critical</em> value of leads to a maximum.
