Surface Areas and Volumes explains the relationship between the length and breadth of a figure. For example, a cuboid is formed by six different rectangles. So, if students want to find the surface area of the cuboid, then they need to find the area of all the rectangles. After finding the areas of all the surfaces, they need to add them, which will give them the surface area of the cuboid.

Similarly, students can also find out the surface area of the cylinder. This chapter is filled with solved examples and exercises. Students must know the correct formulas and how to apply them. Thus, practising the questions is the best way to master this chapter.

Students can also refer to the table below to check the important topics covered in NCERT Class 9 Maths Chapter 13:

To help guide students in their exam preparations for NCERT 9th Maths Chapter 13 Surface Areas and Volumes, we have provided some of the important points to remember below:

- If a cuboid has length l, breadth b and height h, then
- The surface area of the cuboid = 2 (lb + bh + lh)
- Lateral surface area of the cuboid =2 (l + b) × h
- Length of a diagonal = √l
^{2}+b^{2}+h^{2} - Volume of the cuboid = l × b × h

- If the length of each edge of a cube is l, then
- Surface area of the cube = 6l
^{2}= 6(Edge)^{2} - Lateral surface area of the cube = 4l
^{2}= 4(Edge)^{2} - Volume of the cube = l
^{3}= (Edge)^{3}

- Surface area of the cube = 6l
- If r is the radius and h is the height of a right circular cylinder, then
- Curved (lateral) surface area = 2πrh
- Total surface area = 2πr(h+r)
- Volume = πr
^{2}h

**Ans:** Surface Area is the area of the outer part of any 3D figure, and Volume is the capacity of the figure, i.e. the space inside the solid.

**Ans:** If you want to find the surface area of the cuboid, then you need to find the area of all the rectangles. After finding the areas of all the surfaces, you need to add them, which will give you the surface area of the cuboid.
