Surface area | definition of surface area by Medical

surface area: the total area exposed to the outside environment. The surface area of an object increases with the square of its linear dimensions. Volume increases as the cube of the object's linear dimensions. Thus the larger of two objects of the same shape will have less surface area per unit volume than the smaller object. Most loss of
