What is exposed surface area

The exposed surface area is the total area of an object's surface that is not covered or hidden. It is the measurement of the surface area of an object that is directly in contact with the environment. This area plays an important role in various physical, chemical, and biological processes such as heat transfer, chemical reactions, and microbial growth. The exposed surface area can be calculated by measuring the dimensions of the object and determining the areas of all its visible surfaces.
