Chapter 13: Surface Areas and Volumes (Class10)

The chapter Surface Areas and Volumes deals with the study of different three-dimensional solids and the methods to calculate their surface area and volume. This chapter is very important for board examinations and for understanding real-life applications of geometry.

In this chapter, students learn about cuboid, cube, right circular cylinder, right circular cone, sphere, hemisphere, and frustum of a cone. The formulas for curved surface area (CSA), total surface area (TSA), and volume of these solids are explained with proper derivations and examples.

The chapter also focuses on conversion of solids, where one solid is melted or transformed into another solid, keeping the volume constant. Such problems help students develop logical thinking and problem-solving skills.

Real-life problems such as water tanks, pipes, cones, balls, and containers are included to show the practical use of surface area and volume in daily life. This chapter strengthens students’ understanding of geometry and improves calculation accuracy.

Overall, Surface Areas and Volumes is a scoring chapter that plays a vital role in both theoretical knowledge and practical .
