UP Board Class 9 Maths Book – Surface Area and Volume

The chapter “Surface Area and Volume” in the UP Board Class 9 Maths Book helps students understand the measurement of three-dimensional (3D) shapes in terms of their surface areas and volumes. It covers fundamental solids like cubes, cuboids, cylinders, cones, spheres, and hemispheres, providing clear formulas and step-by-step examples to calculate their surface area and volume.

Surface Area and Volume
1 / 0 100%


Students learn how to derive and apply important formulas such as the curved surface area (CSA), total surface area (TSA), and volume for different solids. Real-life applications, such as finding the amount of material required to make containers or calculating storage capacity, make this chapter both practical and engaging.

The UP Board Class 9 Maths Book follows the NCERT-based syllabus, ensuring conceptual clarity through examples, diagrams, and exercise problems. By mastering this chapter, students strengthen their understanding of geometry and measurement, building a strong foundation for higher-level mathematics and competitive exams.
