## CBSE Class 9 Maths Worksheet Chapter 13 Surface Areas and Volumes - Download Free PDF With Solution

In Maths, calculating the remaining space available inside an object and the space taken up by an object is possible, not for two-dimensional figures but for three-dimensional figures. The surface areas and volumes may seem perplexing for most people, but through various worksheets and exercises and with the right guidance, students are able to ace this chapter, making this one of the easiest chapters that can very well guarantee marks for students.

In surface areas and volume for class 9, students will learn what the surface areas and volumes are for certain shapes and how to calculate them by memorising each specific formula.

That being said, what are surface areas and volumes? When it comes to three-dimensional objects, the surface area is the area/region occupied by the surface of any given object. At the same time, the volume is the space available inside that given object. There are different geometrical shapes and sizes whose surface areas and volumes can be calculated, such as the sphere, cube, cuboid, cone, cylinder, etc. Every shape has its own surface area and volume, as well as its own formula used to calculate them.

Many worksheets such as Surface Area and Volume class 9 worksheet, Surface Area and Volume class 9 worksheet with answers, Surface Area and Volume class 9 worksheet PDF, Surface Area and Volume class 9 practice questions and Surface Area and Volume class 9 important questions with solutions PDF will enhance the overall understanding of the students for this chapter.

## Interesting Facts About Surface Areas and Volumes for Class 9

• The surface area of a three-dimensional figure is the space occupied by it.

• There are two types of surface areas :

• Total surface area

• Curved surface area

• The total surface area is the “total” surface area of the figure, including both the base and the curved surface of a figure. (this total area can be found by adding the sum of the above areas)

• The curved surface area signifies the curved surface of the figure that does not include its base.

• The curved surface area of a figure is also called the lateral surface area.

• The amount of space that the figure occupies or takes up is called the volume of the figure and is measured in cubic units.

## What does the PDF Consist of?

• The introduction of technology into the syllabuses of many schools to assist in their learning and teaching processes has been very convenient and reasonable.

• These processes include various assignments, tests, homework and worksheets being handed over to the students via documents online.

## FAQs on CBSE Class 9 Maths Worksheet Chapter 13 Surface Areas and Volumes - PDF

1. Can you calculate the surface areas and volumes for two-dimensional figures?

When it comes to two-dimensional figures, only the area taken up by them can be calculated as the volume isn't available because it doesn’t exist. Figures such as a circle, rectangle, triangle, square, rhombus, etc. are two-dimensional figures.

2. What is the volume of a cuboid?

The volume of a cuboid is the product of all three sides, i.e. l x b x h.

3. What is the surface area of a cube?

The surface area of a cuboid of side a is 6a3.
