If you want to know the surface area of a rectangular prism, also known as a box, you need to add up the areas of all its six sides. You can achieve this by employing the formula 2lw + 2lh + 2wh. In this formula, 'l' stands for length, 'w' for width and 'h' for height. It's essential to use the same units of measurement throughout for a precise outcome.
