10. Mensuration

Mensuration deals with the measurement of areas, surface areas, and volumes of different geometric shapes. In this chapter, students study how to calculate the surface area and volume of three-dimensional solids such as cubes, cuboids, cylinders, cones, and spheres. These formulas help in finding how much space an object occupies or how much material is needed to cover its surface.

 

The lesson also explains problems involving combinations of different solids, where two or more shapes are joined together. Understanding mensuration is very useful in real life for tasks such as construction, designing containers, measuring storage capacity, and engineering applications. This chapter helps students apply mathematical formulas to practical situations involving shapes and measurements.
