## This lesson is about calculation of surface area and volume of different solid structures

### Introduction to CBSE Class 10 Mathematics Chapter "Mensuration-Surface Areas and Volumes"

“Mensuration-Surface Areas and Volumes” is a core chapter in the Class 10 Mathematics curriculum that enhances students’ understanding of 3D shapes, including cylinders, cones, spheres, and hemispheres, along with their combinations. Students learn to calculate the surface area and volume of these solids, which are essential concepts in both theoretical and practical mathematics.

The chapter delves deep into the formulas and methods required to calculate the lateral surface area, total surface area, and volume of these geometric figures. It guides students through solving problems related to the real world, such as determining the amount of material needed for construction, the capacity of containers, and more.

Students are also introduced to the concept of converting one type of solid into another and the calculations involved in such conversion processes. For instance, they explore how to determine the number of spheres that can be molded from a cylindrical rod of metal, or the volume of metal in a hollow spherical shell.
