What are lateral surface areas?

In many mathematical texts, the lateral surface area (L.A.) is given along with—or instead of—the surface area (S.A.). This type of area is the surface area of a three-dimensional figure, excluding the area of any bases. In other words, the lateral surfaces are the side faces (or surfaces) of a solid, or any face or surface that is not a base (or bottom of a figure).
