Application in Real-Life Examples
Knowing the surface area of combination of solids can be very helpful in everyday-life as these combinations can be objects we use in real life as well. Some practical applications include:
- While constructing buildings or structures, civil engineers and architects need to know the surface areas of the complex structures to estimate the amount of paint required, to optimise designs to reduce costs. Etc.
- In designing efficient applications of thermal heat transfers such as refrigerators, cooling systems and radiators, designers need to calculate the surface areas of the surfaces to maximise heat transfer efficiency.
- Medication dosage to patients is given in proportion to the surface area of the individual for its uniform distribution over the body.
These are just a few applications that show us the importance of knowing the concept of surface area and how it is deeply related to our everyday life.
Surface Area of a Combination of Solids
All of us who study the chapters on surface area calculation have at least once wondered how to find the surface area of everyday objects like pencils, buckets, earthen pots and medicine capsules, isn’t it? Well, it isn’t as difficult as it seems- because these objects can be simplified as a combination of simple solid shapes. By the end of this article, you will thoroughly understand how to find the surface area of a combination of solids, right from the basics.
