What is Surface area?
'''Surface area''' is the measure of the [[total]] [[area]] that the [[surface]] of the object occupies ([[3D]] object). The surface area of a [[polyhedron]] is found by finding the [[sum]] of the area of all of the faces. The surface area is found between many [[three-dimensional]] (3D) [[shape]]s using [[formula]]s. The surface area is useful because it tells us how much material is required in order to cover the object—for example, how much [[paint]] is needed to paint a [[Table (furniture)|table]]. Surface area is the sum of the faces, or surfaces, of a three dimensional shape. == Surface area and evaporation == Surface area increases rate of evaporation because there are more molecules touching the surface. There the surface molecules can draw heat energy from the surroundings, which makes the molecules heat up faster and escape faster. This process is also known as evaporation. For example, a bowl filled with water will evaporate much faster than a flask filled with the same amount. == References == {{math-stub}} [[Category:Physical quantity]] [[Category:Geometry]]
