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.
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.
