NCERT Solutions for Class 10 Maths Chapter 13 Ex 13.1

The first exercise of this chapter is based on finding the surface area of a combination of solids. For instance, a combination of a hemisphere and a cylinder, a combination of a cone and a hemisphere, a combination of a cube and a hemisphere, a combination of a cone and a cylinder and more. There are 9 questions in this exercise of word-problems format. You must read the word problems very carefully and make sure to use the right formula for curved surface area and total surface area. Our NCERT Solutions for Class 10 Maths Chapter 13 Ex 13.1 will help you out. 

NCERT Solutions for Class 10 Maths Chapter 13 Ex 13.2 

The second exercise of this chapter is based on finding the volume of a combination of solids. There are 8 questions in this exercise and all of them are word problems. You must read them carefully and take note of all the data that is given to you. In some questions, the volume of a combination of solids would increase after the combination while in some questions it would increase. We have provided stepwise solutions for the exercise. Check them if you get stuck at any point in solving this exercise.

The third exercise of the chapter is based on finding the surface area and volume on converting one solid to another. For instance, a cuboid might be melted and converted into several cubes, or a cone may be converted into a sphere. You have to read the questions carefully and determine whether you have to find the volume or surface area. The exercise includes 9 interesting word problems. Make sure you match your answers with our NCERT Solutions. 

NCERT Solutions for Class 10 Maths Chapter 13 Ex 13.4 

The fourth exercise of the chapter is based on finding the curved surface area, total surface area and volume of the frustum of a cone. The frustum of the cone is obtained when we slice (or cut) through a cone with a plane parallel to its base and remove the cone that is formed on one side of that plane. For instance, a bucket is in the shape of a frustum of a cone. The exercise includes 5-word problems. This is a new concept so practice all the questions very carefully.
