Chapter 11 Mensuration Ex 11.3 of NCERT Class 8 Maths book includes how to find the surface area of a cube, cuboid and cylinder. You must understand that the surface area of a solid is the total area occupied by a three-dimensional object. It can be categorised as total surface area and curved surface area. The Total Surface Area considers all the faces of the three-dimensional shape including the flat surfaces and the curved surfaces. The Curved Surface Area is the area occupied by the curved surface of the shape. It does not include the area of the bases.
The following formulae will help you in solving this exercise better:
|
Solid Shape |
Total Surface Area (TSA) |
Curved Surface Area (CSA) |
|
Cube |
6a2 |
4a2, where a is the length of each side |
|
Cuboid |
2 (lb + bh + lh) |
2h (l + b), where l, b, and h are the length, breadth, and height of the cuboid |
|
Cylinder |
2πr(h + r) |
2πrh, where r is the radius and h is the height of the cylinder |
