Claudia works as a manufacturer of decorative jewelry boxes. A customer would like her to create some boxes with the following conditions:

The sum of the length and width must be 30 centimeters.
The height must be 3 centimeters less than the length.
The box should have the greatest possible volume.

Let's do some math to see if we can decide what size boxes Claudia needs to make, and show what we know about polynomials in the process. Remember: One formula we can use to find the volume of a box is Length * Width * Height.
