surface area
Skin's total size
Surface area is the total area of the outer surfaces of a three-dimensional object.
In geometry, formulas calculate surface area for regular shapes: the surface area of a sphere.
The concept matters in science and engineering where interaction with surroundings depends on exposure: Smaller particles have more surface area relative to their volume.
