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:
“Puritanism, in whatever expression, is a poisonous germ. On the surface everything may look strong and vigorous; yet the poison works its way persistently, until the entire fabric is doomed.”
—Emma Goldman (1869–1940)
