Plug in the variables and solve the equation. where l is the length, w is the width, and h is the height of the box. Click the Calculate button for all fields to be calculated. The surface area of the box is: A 2 l w + 2 l h + 2 w h. This yields a product called the area, which is expressed. For a square you only need to find the length of one of.
