In geometry, the lateral surface of a solid is the face or surface of the solid on its sides. That is, any face or surface that is not a base. Lateral surface area means the area of 4 sides. Take for example a cube. Consider the edge of the cube as a. Area of one square = a*a = a2. Thus the lateral surface of a cube will be the area of four faces: a*a*4 = 4a2.
Famous quotes containing the word surface:
“We tend to be so bombarded with information, and we move so quickly, that there’s a tendency to treat everything on the surface level and process things quickly. This is antithetical to the kind of openness and perception you have to have to be receptive to poetry. ... poetry seems to exist in a parallel universe outside daily life in America.”
—Rita Dove (b. 1952)
