If a rectangular cuboid has length , width , and height , then: [6] its volume is the product of the rectangular area and its height: V = a b c . {\displaystyle V=abc.} its surface area is the sum of the area of all faces: A = 2 ( a b + a c + b c ) . {\displaystyle A=2(ab+ac+bc).}
Example of a quadrilateral-faced non-convex hexahedron. In geometry, a cuboid is a hexahedron with quadrilateral faces, meaning it is a polyhedron with six faces; it has eight vertices and twelve edges.
The volume of a cuboid is the product of its length, width, and height. Because all the edges of a cube are equal in length, the formula for the volume of a cube as the third power of its side length, leading to the use of the term cubic to mean raising any number to the third power: [ 7 ] [ 6 ] V = a 3 . {\displaystyle V=a^{3}.}
V-Cube 6 in original packaging. The V-Cube 6 is a 6×6×6 version of the original Rubik's Cube. The first mass-produced 6×6×6 was invented by Panagiotis Verdes and is produced by the Greek company Verdes Innovations SA. Other such puzzles have since been introduced by a number of Chinese companies, most of which have mechanisms which improve ...
The term unit cube or unit hypercube is also used for hypercubes, or "cubes" in n-dimensional spaces, for values of n other than 3 and edge length 1. [1] [2]Sometimes the term "unit cube" refers in specific to the set [0, 1] n of all n-tuples of numbers in the interval [0, 1].
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.The distance between any point of the circle and the centre is called the radius.
