CBSE Class 10 Maths Chapter 12 Surface Areas and Volumes Syllabus 2026–27

Surface Areas and Volumes chapter deals with measuring three-dimensional shapes and understanding how their surfaces and volumes are calculated. It introduces formulas for different solids such as cubes, cuboids, cylinders, cones, and spheres. You will also learn how to solve problems involving combinations of these shapes and the conversion of solids from one form to another. 

The chapter requires careful application of formulas and accurate calculations. A clear understanding of these concepts is important for solving practical geometry questions and improving performance in board exams.
