To measure the surface area of a box, I would first identify and measure the length, width, and height of the box. Then, I would calculate the surface area by using the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the box. Once I have calculated the surface area using these measurements, I would have the total amount of space that the box covers on all sides.
