How to calculate the surface area of a box?
Surface area of a box. The surface area formula for a rectangular box is 2 x (height x width + width x length + height x length), as seen in the figure below: Since a rectangular box or tank has opposite sides which are equal, we calculate each unique side’s area, then add them up together, and finally multiply by two to get the total surface area.
