NCERT Solutions for Class 8 Maths Chapter 11 Mensuration
In previous grade, students learnt about area and perimeter of closed plane figures such as circle, square, triangles, rectangles etc. In Class 8 CBSE Maths Chapter 11, students will learn about 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. NCERT Solutions for Class 8 Maths Chapter 11 try these problems with answers to top the concept because Mensuration is a topic widely used in real-life applications.
The topics discussed in the chapter revolves around:
1. Area of
(i) a trapezium = half of the sum of the lengths of parallel sides × perpendicular distance between
(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
