What is Surface Area and how to calculate it
In the previous part you have learned how to calculate the area of various polygons. The next step is to calculate the surface area of 3D figures! This is nothing to worry about for all you have to do is calculate the area of all individual faces (sides) and add them all up at the end. However, many students make mistakes when doing so. So study all the videos during your maths revision (I will add new important information in each video) and learn what surface area is and how to calculate the surface area of an object.
