Mathematics is one of the most rewarding subjects, especially for students dreaming to appear in future government competitive exams like SSC, NDA, Railway, Banking, State PCS, and more. And one of the most fundamental building blocks for these exams is - Surface Area and Volume (Chapter 12, Class 10 NCERT).

The chapter beautifully introduces how to compute surface area, total surface area, and volume of everyday 3D objects - cylinders, cones, spheres, and even complex structures formed by combining two or more shapes. Mastering this will not only help you board exams but also pave the path for your competitive journey.

✦ Why This Chapter Matters for Aspirants?

Because many exam questions - especially in SSC GD, CGL, CHSL, RRB Group-D, PSU Exams & Defence recruitment tests - directly use formula-based problems from this chapter. A strong grip here gives you a tremendous advantage later.


What You Will Learn:

🔹 Exercise 12.1 – Surface Area of Combined Solids

Understand how to add or subtract areas when two shapes merge. Perfect for students who struggle with visualizing 3-D geometry.

🔹 Exercise 12.2 – Volume of Combined Solids

Learn how volumes interact - when two objects join, how we calculate their combined space.

How to Study This Chapter Effectively

1. Start with Concept Building

Know the formulas - TSA, CSA, Volume of Cone, Sphere, Cylinder, Cube & Cuboid.

2. Practice Step-wise

Attempt each question without looking at the answer. Solutions act as a guide - not a shortcut.

3. Draw Figures

Visualizing shapes helps you avoid confusion.

4. Attempt Previous Year Board Questions

Boards & competitive exams DO repeat similar patterns.
