Class 10 Mathematics Revision Notes for Surface Areas and Volumes of Chapter 13
The course and curriculum of Class 10 are vast and indepth. It does require hard work and consistent practice to score good marks in examinations. Students have to continuously revise and practice Class 10 Mathematics Chapter 13 Notes to master all the concepts. To make it easy for students, Extramarks has provided an entire list of Class 10 Mathematics Revision Notes for Surface Areas and Volumes of Chapter 13 which can be accessed with a click. Apart from revision notes, students can also access CBSE Syllabus with notes, CBSE Previous Questions, CBSE Important Questions, previous question papers, etc. The notes have been prepared after referring to NCERT books and CBSE guidelines.
Class 10 Mathematics Revision Notes for Surface Areas and Volumes of Chapter 13
Let Us Take a Quick Look at the Surface Area and Volume of a Few Geometrical Shapes
Chapter 13 of Class 10 Mathematics is about the Surface Area and Volume of a Few Geometrical Shapes. A cuboid has three dimensions: width, length, and height. The surface area of the cuboid may be calculated using these dimensions. There are three pairings since there are six surfaces. Knowing how to compute the lateral surface area of each of the three pairings will assist you in determining the formula. This formula applies to every cuboid and may be used to compute its lateral surface area. Likewise, if you continue to the cylinder shape, you will become acquainted with the notion of curved surfaces.
Why Should You Use Class 10 Revision Notes Maths Ch 13?
The Class 10 Revision Notes Mathematics Ch 13 that are available on the Extramarks website have been developed in a way that clears the doubts and queries of students properly. Extramarks notes for Surface Areas and Volumes will help students in knowing about the derivation of the formulas as well as utilizing them in solving the questions. The whole chapter will be thoroughly defined and clarified so that students may answer questions independently.
Find the relevant portions in the notes to thoroughly comprehend the individual 3D forms and understand the formula with better clarity. With the aid of these notes, determine the distinctions between curved and lateral surface area and how the formulae are generated to calculate them.

Surface Area
Surface area refers to the area occupied by a threedimensional object. The surface area of this threedimensional item is equal to the sum of the areas of the twodimensional faces.
Basically, the Surface Area Can Be Classified As
Surface area can be classified into the following:
 Curved Surface Area (CSA)
An object’s curved surface area is the total area of all its curved surfaces.
 Lateral Surface Area (LSA)
The lateral surface of an item is the area of its face minus the areas of its top and bottom.
 Total Surface Area (TSA)
The total surface area is the sum of all the faces and bases.
Volume
The volume of a threedimensional object is used to measure the space it occupies. Because the volume of a solid object is the product of its three dimensions, it is given in cubic units.
Important Formulas for Surface Areas and Volumes
Following are the important formulas for surface areas and volumes:
 Lateral/ curved surface area
 Total surface area
 Volume related to 3d shapes (solid shapes)
Surface Area and Volume of Cuboid
Following are the formulas for surface area and volume of cuboid:
Lateral Surface Area of a Cuboid
Lateral surface area of a cuboid = 2(width×height) + 2(length×height)
Total Surface Area of a Cuboid
Total surface area of a cuboid = 2 (length×width) + 2(width×height) + 2(length×height)
Volume and Surface Area of Cube
Following are the formulas for the surface area and volume of a cube:
The Lateral Surface Area of a Cube
The lateral surface area of a cube = 4(side)^2
Total Surface Area of a cube
Total surface area of a cube = 2×(3side2)
Surface Area and Volume of Right Circular Cone Right Circular Cylinder
Following are the formulas for the surface area and volume of a right circular cylinder:
Lateral surface area or curved surface area of right circular cylinder = 2⊼*radius*height
Total Surface Area of Right Circular Cylinder
Total surface area of right circular cylinder = 2⊼*radius (height + radius)
Volume
The volume of the right circular cylinder(V) = area of the circular base x height of the right cylinder
The volume of the right circular cylinder = ⊼*radius^2*height
Surface Area and Volume of Right Circular Cone
Following are the formulas for the surface area and volume of the right circular cone:
Curved Surface Area
Curved surface area = ½ (circumference of base)*(slant height)
Total Surface Area
Total surface area = ⊼*radius(l+r)
Volume
Volume = ⅓ ⊼*radius^2*height
FAQs (Frequently Asked Questions)
1. What exactly is surface area?
The surface area of a threedimensional form is the amount of space surrounding it.
2. What is the definition of volume?
A liquid, solid, or gas’s volume is the amount of threedimensional space it occupies.
3. What exactly is a 'cubic' measurement?
It is a volume measurement unit (like a cubic inch or a cubic centimetre).
4. How to compute the volume of hemisphere on cube or hemispherical cavity on cube?
Volume can be computed in the following manner.
Volume = Volume of cube + Volume of hemisphere = a^3 + 2/3 ⊼*radius^3
=a^3 + 2/3 ⊼*(a/2)^3
