Area is the measure of how much surface an object has.
area
Surface area is the total area that the surface of a three-dimensional object occupies, measured in square units. It represents the amount of exposed area of an object, which is crucial for applications like painting or wrapping. Volume, on the other hand, is the measure of space that a three-dimensional object occupies, expressed in cubic units. It quantifies how much substance can fit inside the object, making it essential for tasks like filling containers.
Surface area is the total area that the surface of a three-dimensional object occupies. It is measured in square units and represents the sum of the areas of all the outer faces of the object. For example, in geometric shapes like cubes or spheres, surface area calculations help determine how much material is needed to cover the object or how much exposure it has to the environment. Understanding surface area is crucial in various fields, including architecture, manufacturing, and biology.
That is called the area.

area
The measure of how much surface an object has is called surface area. It is calculated by finding the sum of the areas of all the faces of the object. This measure helps in determining the amount of material needed to cover or coat the object.
The total area of all surfaces of an object is called the surface area. It is a measure of how much exposed surface the object has.

The measure of how much stuff something has is called its mass. It is a measure of the amount of matter in an object and is typically measured in units such as grams or kilograms.
You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
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.
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.
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
