Chapter Overview
This chapter helps you understand and calculate the surface areas and volumes of various 3-dimensional shapes such as cubes, cuboids, cylinders, cones, spheres, and hemispheres. It also introduces the concept of converting one solid into another and finding the volume of a combination of solids.
Important Keywords
- Surface Area: The total area of all the outer surfaces of a 3D object.
- Volume: The amount of space occupied by a 3D object.
- Curved Surface Area (CSA): The area of only the curved surface of a solid.
- Total Surface Area (TSA): The sum of all surfaces (curved + flat) of a solid.
- Combination of Solids: A figure formed by merging two or more solids (e.g., cone on a cylinder).
