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:
“All the aspects of this desert are beautiful, whether you behold it in fair weather or foul, or when the sun is just breaking out after a storm, and shining on its moist surface in the distance, it is so white, and pure, and level, and each slight inequality and track is so distinctly revealed; and when your eyes slide off this, they fall on the ocean.”
—Henry David Thoreau (1817–1862)
