A cube has 6 faces, 12 edges, and 8 vertices. Because the cube has 12 edges and all of them are the same length, the perimeter of the cube is: The perimeter of a cube is determined by the number of edges and the length of the edges. Lateral Surface Area of a Cube = 4a 2 Perimeter of a Cube Because a cube has four side faces, its lateral area is the total of the areas of all four side faces. The lateral area of a cube is the sum of the areas of the cube’s side faces. Surface Area of a Cube = 6a 2 LSA of a Cube Surface Area of a Cube = 2 (l x b + b x h + h x l) = 2 (a x a + a x a + a x a) = 2 (3a 2 ) = 6a 2 Let us assume the length of a cube as ‘a’. The length, breadth and height of a cube are all equal. Perimeter of a Cuboid = 4 (l x b x h) TSA of a Cube Because the cuboid has 12 edges and the values of those edges varied, the perimeter is given by: The cuboid’s perimeter is determined by its length, width, and height. Cubic units are used to represent the volume of a cuboid. The volume of a cuboid is determined by its length, width, and height. The volume of a cuboid is the amount of space occupied within a cuboid. Square units are used to represent the surface area of a cuboid. What is Area of Trapezium, Parallelogram, and Rhombus? Examples of CuboidĪ few examples of cuboids in our daily lives are tall buildings, books, boxes, mobile phones, televisions, microwaves, photo frames, mattresses, bricks, etc. Length of diagonal of cuboid = √ (l² + b² + h²) The length of the longest diagonal of a cuboid is given by Where l is the length, b is the base and h is the height of the cuboid. The volume of a cuboid can be found by multiplying the base area with the height. Lateral surface area of a cuboid = 2(l+b)h Volume of Cuboid The formula to calculate the lateral surface area of a cuboid isĪrea of four sides = 2 ( l × h ) + 2 ( b× h ) = 2 ( l + b ) × h = perimeter of base ×height An example of the lateral surface area is the sum of the area of the four walls of a room. leaving the bottom and the top face gives the lateral surface area of a cuboid. Total surface area of a cuboid = 2 Browse more Topics under Mensuration If l is the length, b is the breadth and h is the height of the cuboid, then the sum of areas of six rectangles of a cuboid gives the total surface area of the cuboid. It has 6 surfaces of which each opposite pair is of the same dimensions.ĭownload Mensuration Cheat Sheet PDF Below Also, the opposite faces are always equal. In a cuboid, each face is a rectangle and the corners or the vertices are 90-degree angles. As a result, 4 space diagonals can be drawn within it. The space diagonals run through the cuboid’s interior. There can be a total of 12 face diagonals in a cuboid.Ī space diagonal is a line segment that connects a cuboid’s opposite vertices. For example, AC is a face diagonal for the Face ABCD. All of the angles created at a cuboid’s vertices are right angles.įace diagonals can be created by connecting the opposite vertices on a cuboid’s face. Opposite edges in a cuboid are parallel to each other.Ī cuboid has 8 vertices. For example, AB=DC=HG=EF, AD=BC=HE=GF, AH=BG=DE=CF. In a cuboid, the opposite edges are of equal lengths. They are AB, BC, CD, AD, DE, EF, FC, AH, HG, GB, HE, GF. There are a total of 12 edges in a cuboid. A cuboid’s faces are all rectangular in shape. For example, ABCD and HGFE are two opposite faces. Two opposite faces in a cuboid are of equal lengths and areas. In the figure above, ABCD, DEFC, BCFG, ABGH, HEFG, ADEH are the 6 faces of cuboid. What is Area of Rectangle? Faces, Vertices and Edges of CuboidĪ cuboid is made up of a total of 6 rectangles, and each rectangle is called a face. It is one of the most prevalent shapes in our environment, with three dimensions: length, breadth, and height. The cuboid shape has a closed three-dimensional structure surrounded by rectangular faces, which are rectangle plane sections.
