What is the formula of finding the surface area of a square?
To find the surface area of a square you measure 1 side (people mainly choose the left side). Say that side was 6 inches. Then you know it is a square so all or the sides are equal. So the side adjacent to it (the top or bottom side) is also 6 inches. The side has to be adjacent to it or it won’t work. Then you multiply the height by the length (6 * 6) to get the area.
