it stands for the total surface area
The surface area is L*B where L is the length of the rectangle and B is the breadth.
"Surface area" is the covering of a multi-dimensional body. It is the area that the outside of a body has.For exampleA cube has a surface area of 6 * L2 where L is the length of one side. (six sides to the cube, each is a square with area L * L)
Total surface area = 2*(L*B + B*H + H*L) square units where L = length, B = breadth and H = height.
The surface area of a cuboid is 2*(L*B + B*H + H*L) where L = length, B = breadth and H = height. In a cube, L = B = H and so surface area = 6*L2
