4. Challenge Problem
An open-top box is made from a 14-inch-by-32-inch piece of cardboard. Sally does not know how much she needs to cut for the height of the box. We will use “x” as the known variable for the height.

5. Challenge Problem
Write the volume of the box as a polynomial function in standard form. Hint: You need to know the volume formula of a rectangular prism.
Find the volume of the box is the height is 2 inches.
