NCERT Solutions for Class 9 Maths Chapter 13: Surface Areas and Volumes - Exercise 13.5

## FAQs on NCERT Solutions for Class 9 Maths Chapter 13: Surface Areas and Volumes - Exercise 13.5

1. What topics are covered in NCERT Solutions for Class 9 Maths Chapter 13 Surface Areas and Volumes (Ex 13.5) Exercise 13.5?

The NCERT Solutions for Class 9 Maths Chapter 13 Surface Areas and Volumes (Ex 13.5) Exercise 13.5 relies on the concept that the space occupied by the object is measurable and is known as the volume. In this exercise we will deal with the question related to volume. If the object is hollow, the volume of any substance that can be filled inside the hollow object is referred to as the container's capacity. As a result, in either case, the unit of measurement is a cubic unit.

2. What are the formulas used in the NCERT Solutions for Class 9 Maths Chapter 13 Surface Areas and Volumes (Ex 13.5) Exercise 13.5?

In NCERT Solutions for Class 9 Maths Chapter 13 Surface Areas and Volumes (Ex 13.5) Exercise 13.5 the concept of volume is used. The volume of cuboid and cube formulas are given below:

Cuboid volume is given by: length × breadth × height

Volume of a Cube is given by: $x^3$ where 'x' is the cube's edge.

Their unit of measurement is cubic units.

3. What considerations should be used when determining the volumes of various shapes?

Any object's volume is the amount of space it takes up. The amount of space occupied is determined by the shape of the object. Before calculating the volume of any shape, make sure that all measurements are in the same unit. If one measurement is given in centimetres and the other in metres, convert both before calculating the volume.

4. How can I cover NCERT maths chapter 13 Surface Area and Volume without becoming bored?

NCERT maths chapter 13 Surface Area and Volume is a lengthy chapter that covers many important topics. For exams, you must practise exercises and example questions. To learn the chapter in an effective manner you can break up the monotony by studying an easier chapter in between. Practice problems from previous years. The visual aid will help you remember the concepts and reduce boredom while studying.

5. Why do we study volume and surface area?

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much space an object has. It is significant because, in real life, we consider the surface areas of various objects when wrapping, painting, and ultimately when creating things to achieve the optimal design.
