What is Surface Area?
Surface area is the total area occupied by the surface of a three-dimensional object. It is the sum of the areas of all the surfaces of the object.
Total Surface Area (TSA)
This term is typically used for objects that have both curved and flat surfaces, such as cylinders, cones, and spheres. TSA includes the area of all surfaces of the object, including both the curved and the flat surfaces.
Curved Surface Area (CSA)
This term usually refers to the area of only the curved surface of an object, excluding any flat surfaces. It’s often used in the context of cylinders, cones, and other similar shapes. For instance, the CSA of a cylinder is the area of its lateral surface, which is the curved part, while the bases (top and bottom) are excluded.
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.
