Question

An open-top box is created by cutting out corners from a piece of cardboard as pictured below. Find a function that models the surface area as a function of x.

This image shows a geometric diagram representing the net of a rectangular box. The net consists of six connected rectangles and is labeled with dimensions.

- The central rectangle measures 20 inches in length and an unspecified width represented by "x".
- Attached to the width sides of this central rectangle are two pairs of rectangles. Each of these rectangles has a width of 12 inches and a length represented by "x". These rectangles form the sides of the box when folded.
- The diagram includes arrows indicating the direction the sides of the net fold to form the box.

This net will fold into a three-dimensional box, with the central rectangle serving as the bottom or top face, and the flanking rectangles folding to become the sides, front, and back.
