Area is the measure of how much surface an object has.
area
Volume is how much an object can store - like how much can you put inside a box. Surface area is the sum of the area of an objects surfaces - such as if you have a box, find the area of one side. Then you just multiply it by 6 (because a box have 6 faces) to get the total area of an object's surface.
That is called the area.
No volume is how much space an object takes up. Mass is the measure of the amount of matter in an object.

Surface area.
You can measure its length, or its volume, or its surface area, or its projected area (in effect the area of its shadow).
First measure the surface area in m2. Then the mass in kg. Divide the surface area by the mass. Now you have your surface area to mass ratio as m2/kg, or verbally, square metres of area per kilogram of mass. So how to measure the surface area? Well, if it is a human body you can calculate it using one of the common formulae available, such as Mosteller or Dubois and Dubois, from mass and height. If it is an odd-shaped inanimate object, you could measure the m2/litre properties of a sticky liquid, then measure how much volume is used to coat the object. You could experiment with some simple shapes first to validate your method.
SI units are pascals 1 pascal = 1 newton over 1 square metre The standard unit is the pound per square inch (psi), which equals 6894.757 pascals.
Designers must know the volume and surface area of an object because they must know how much space the object has inside it to put mabey parts in the object and to see how much the object weighs to see if it can fit somewhere without breaking it
The amount of space on the surface of an object is known as its surface area. In chemistry, it is a general rule that as the surface area of a substance increases, so too does the rate of chemical reaction.

Mass, the bearing surface (how much weight on what surface area), and a "coefficient of friction", a measure of how rough or smooth the surface is.
