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:
“How easily it falls, how easily I let drift
On the surface of morning feathers of self-reproach:
How easily I disperse the scolding of snow.”
—Philip Larkin (1922–1986)
