What is a cuboid Class 6?
In geometry, a cuboid is a solid shape or a three-dimensional shape. A convex polyhedron that is bounded by six rectangular faces with eight vertices and twelve edges is called a cuboid. A cuboid is also called a rectangular prism. A cuboid with six square faces is called a cube.
A cube has all sides equal (squares). A box can have different length, width and height. A box is generally called a cuboid, but could be a cube.
The key difference between a cube and a cuboid is: a cube has six square-shaped faces of the same size, but a cuboid has rectangular faces. Although both cubes and cuboids look the same in structure, they have a few different properties based on edge length, diagonals and faces.
Cube Vs Cuboid
All the edges(sides) of a cube are equal i.e the measures of length, breadth, and height are equal. All the edges(sides) of a cuboid are not equal i.e the measures of length, breadth, and height are not equal. All the six faces of a cube are square shapes. Examples of cuboids are Bricks, Duster.
In Maths or in Geometry, a Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges.
Length = Breadth = Height = a. Thus, the measure of each edge of the cube = a. Therefore, the volume of cube formula is a × a × a = a3. It is to be noted that the number obtained using cube formula is the perfect cube number.
A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square.
For example, furniture, books and TV are in the shape of a rectangular box. This shape is a cuboid. On the other hand, objects such as ice, dice and Rubik's cube are examples of another 3D shape called a cube.
The number of cubes in each layer is the length x width of the cuboid. 4 x 3 = 12 so there are 12 cubes in each layer. There are 3 layers in total, so three layers of 12 cubes. 12 x 3 = 36 so there are 36 cubes inside the cuboid.
A cube is a solid shape with six square faces. Each square face has the same side length and thus all the faces have the same size. A cube has 12 edges and 8 vertices. Each vertex refers to a corner where three edges of a cube meet. We can observe several examples of the cube shape in our everyday life.
What is the difference between cube and Rectangle?
The distinction between a rectangle and a cube is that a rectangle is a two-dimensional form in which the geometry's length and breadth are specified. A cube is a three-dimensional figure whose length, width, and depth are all determined.
cube, in Euclidean geometry, a regular solid with six square faces; that is, a regular hexahedron. hexahedron. Related Topics: polyhedron.
A cuboid is a 3D shape that has six faces, twelve edges and eight vertices. Each of its faces is a rectangle. A cuboid is also a prism, as it has the same cross-section all the way through.

Cubes and Cube Roots List of 1 to 15.
| Number | Cube(a3) | Cube root ∛a |
|---|---|---|
| 5 | 125 | 1.710 |
| 6 | 216 | 1.817 |
| 7 | 343 | 1.913 |
| 8 | 512 | 2.000 |
A perfect cube of a number is a number that is equal to the number, multiplied by itself, three times. If x is a perfect cube of y, then x = y3. Therefore, if we take the cube root of a perfect cube, we get a natural number and not a fraction. Hence, 3√x = y. For example, 8 is a perfect cube because 3√8 = 2.
A room is in the shape of a cuboid, with dimensions 12m × 10m × 3m.
Once we've worked out the square, we just need to multiply it by the original number again. In this case, the cube of 5 is 25 × 5 = 125. This can also be expressed as 5³ = 125.
A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°). The opposite sides of a rectangle are equal and parallel.
ABCD is a rectangle. Prove that the centre of the circle through A, B, C, D is the point of intersection of its diagonals. Therefore, it is proved that the centre of the circle through A, B, C, D is the point of intersection of its diagonals.
Fast forward to now, and TVs are a rectangular shape and some television programs and movies are filmed in a wider-than-widescreen format.
Is the volume of a cube equal to the volume of a cuboid?
Volume of cuboid is the product of length, width and height. Volume of cube is equal to the cube of its side (all the sides are equal in length).

Difference of Area and Volume of Shapes.
| Name of the shape | Volume |
|---|---|
| Cube | Side3 |
| Cuboid | Length × Width × Height |
| Sphere | (4/3)πr3 |
| Hemisphere | ⅔ (πr3) |
A cube & Cuboid have the same volume the dimensions of the cuboid are in the ratio 1:2:4.
∴ cube has greater volume.
Length = Breadth = Height = a. Thus, the measure of each edge of the cube = a. Therefore, the volume of cube formula is a × a × a = a3. It is to be noted that the number obtained using cube formula is the perfect cube number.
