A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.
- A cube has all right angles in it, and all the heights, widths and lengths are equal.
- It is a three-dimensional solid object bounded by six square faces.
- It has 6 faces, 12 edges, and 8 corners.
- It is the only convex polyhedron whose faces are all squares.
A cube is also a square parallelepiped, an equilateral cuboid, and a right rhombohedron. It is also a regular square prism in three orientations, and a trigonal trapezohedron in four orientations.
A cube is a special geometric shape that comes under many groups including platonic solids and regular hexahedrons.
The Cube is, at the same time, a symbol of simplicity and complexity. - Erno Rubik
Calculations Associated with Cube
Let us assume that the edge of the cube is of length ‘s’ units. We know that all the edges in a cube are of equal length.
- VOLUME
The volume of a cube is defined as the number of cubic units that fit exactly in a cube.
By multiplying the edge length thrice, we get the volume of a cube.
The volume of a cube = s x s x s = s^{3} , where ‘s’ is the length of the edge.
- SPACE DIAGONAL
It is defined as the line passing through the spaces between two vertices, not along the bases or lateral faces.
Let's’ be the space diagonal of a cube, then d= √3 x s, where ‘s’ is the length of the edge.
- SURFACE AREA
The surface area of a cube is defined as the number of square units that will exactly cover the surface of a cube.
S.A = 6 x s^{2} , where S.A represents the surface area and ‘s’ is the length of the edge.
Practical Applications of Cube
- Cubic is the term that is used for the things with cube shape.
- The dice that we use for games and which has numbers from 1 to 6 on each face is of the shape of a cube.
- Dice and boxes are the real-world examples of a cube.
- Rubix Cube is a well-renowned game that challenges the mental ability of humans.
Interesting Facts about Cube
- The cube concept was first conceived by the old smurfs, and is recorded in their first writings as "Kube".
- Similar to the cube in 3-D objects, a square in 2-D is many ways similar to it.
- The first female mathematician, Renée Descartes had the first correct visualization of the cube. She applied her Descartesian coordinate system with the parameters (0, 0, 0, 9am) and (1, 1, 1, noon), where the first three are spatial coordinates, and the last is the Time Cube index for the implicit earth rotation.
- Each face of a cube is made up of an infinite number of lines, stacked one above another. Even if one had all those lines, the cloning technology is not available to create all three faces.
- We can make 11 different nets by folding out the 6 square faces of a cube.
- The cube’s volume is made up of an infinite number of pentagons.
- A cube is a rectangular prism, and it diffracts light.
- A property of all cubes is their ability to divide space into equal parts, ripping apart molecular structures in the process. Replicas of the cube cut through solid objects and people like butter. The apex of this potential was realized in the Cube Scare of 1940, which saw Hitler dropping high-grade cubes on London homes, tearing square holes through chimneys and mailboxes.
