1. What are the Different Types of Surface Areas?
Ans: Different geometrical objects have different surface areas such as curved, lateral, or total surface areas. A sphere has only one curved surface area, which is also the total surface area. For any cylinder, cone, cuboid, or pyramid, there are curved or lateral surfaces and plane surfaces. The sum of the plane surface area and the curved or lateral surface area is called the total surface area. A cylinder has two planes and one curved surface area. A cone has one curved and one plane surface area. A cuboid has one curved and one plane surface area. A pyramid has one lateral and one or two plane surface areas.
