#class8 #vikramsirclass8 #2023 #ncert #cbse #education #mathematics #mensuration Hello Bachcho kya haal chal ? My name is Vikram And Welcom to My Youtube Channel. About this Video :- Class 8 | Mensuration | ( Example 3)| Chapter 9 | New book 2023-24 || Vikram sir The topics discussed in the chapter revolve around: 1. Area of: (i) a trapezium = half of the sum of the lengths of parallel sides × perpendicular distance between them. (ii) a rhombus = half the product of its diagonals. 2. Surface area of a solid is the sum of the areas of its faces. 3. Surface area of a cuboid = 2(lb + bh + hl) a cube = 6l2 a cylinder = 2πr(r + h) 4. Amount of region occupied by a solid is called its volume. 5. Volume of a cuboid = l × b × h a cube = l3 a cylinder = πr2h 6. (i) 1 cm3= 1 mL (ii) 1L = 1000 cm3 (iii) 1 m3 = 1000000 cm3 = 1000L The main topics covered in this chapter include: Exercise Topic 9.1 Introduction 9.2 Let us Recall 9.3 Area of Trapezium 9.4 Area of a General Quadrilateral 9.5 Area of a Polygon 9.6 Solid Shapes 9.7 Surface Area of Cube, Cuboid and Cylinder 9.8 Volume of Cube, Cuboid and Cylinder 9.9 Volume and Capacity In the previous grade, students learnt about the area and perimeter of closed plane figures such as circles, squares, triangles, rectangles etc. In Class 8 CBSE Maths Chapter 9, students will learn about the surface area and volume of solids such as cube, cuboid and cylinder, area of trapezium, area of quadrilateral, area of special quadrilaterals, area of a polygon, solid shapes, volume and capacity. Students can access this chapter’s NCERT Solutions for Class 8 for solving the exercise problems. Topics Covered: Finding the area and perimeter of a square, rectangle, triangle, polygon, trapezium, circle, as well as a general quadrilateral, determining the surface area (total, lateral or curved) of cubes, cuboids, and cylinders along with their volumes are the scope of topics that fall under class 8 maths NCERT solutions chapter 9 NCERT solutions for class 8 maths chapter 9 mensuration builds on concepts of area and perimeter of figures like triangles, rectangles, etc., that kids learned in previous chapters in order to introduce them to more plane figures and three-dimensional solids. This lesson seamlessly integrates different concepts so that students can apply these to real-life questions. In addition to this, it brings in the topic of volume and capacity. Volume can be defined as the space occupied by a 3D solid shape while capacity is the amount of liquid a container holds. NCERT solutions class 8 maths chapter 9 targets cubes, cuboids, and cylinders. Children learn about the surface area and volume of these figures in-depth. This chapter is not only important for class 8 but also is a crucial topic that makes its way in higher classes. Thus, it is imperative for children to build a strong foundation of this subject matter.
