A cuboid is a three-dimensional Shape. The cuboid is made from six rectangular faces, which are placed at right angles. The total surface area of a cuboid is equal to the sum of the areas of its six rectangular faces. See more Consider a cuboid whose length is “l” cm, breadth is b cm and height h cm. Area of face ABCD = Area of Face EFGH = (l × b) cm2 Area of face AEHD = Area of face BFGC … See more Lateral surface area (LSA) is the area of all the sides apart from the top and bottom faces. The lateral surface area of the cuboid = Area of face … See more For cube, length = breadth = height Suppose the length of an edge = a Total surface area(TSA) of the cube = 2(a × a + a × a + a × a) TSA(cube) = 2 × (3a2) = 6a2 See more A cuboid whose length, breadth and height are all equal, is called a cube. It is a three-dimensional shape bounded by six equal squares. It has 12 edges and 8 vertices. See more WebNCERT Solutions for Class 9 Maths Chapter 11 Constructions Ex 11.2.
