Is surface area and total surface area the same?
Surface area means all the area that you can see in two dimensions – this means the length and width. The surface area of a wall is everything you can paint. … Total surface area in that case means
adding up the areas of all the surfaces
. For a cube, that means adding up the surface area of all six sides.
