9-cube. In geometry, a 9-cube is a nine- dimensional hypercube with 512 vertices, 2304 edges, 4608 square faces, 5376 cubic cells, 4032 tesseract 4-faces, 2016 5-cube 5-faces, 672 6-cube 6-faces, 144 7-cube 7-faces, and 18 8-cube 8-faces . It can be named by its Schläfli symbol {4,3 7 }, being composed of three 8-cubes around each 7-face.
The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3 . The cube is also the number multiplied by its square : n3 = n × n2 = n × n × n. The cube function is the function x ↦ x3 (often denoted y = x3) that maps a number to its cube. It is an odd function, as.
3D model of a cube. In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets, or sides, with three meeting at each vertex. Viewed from a corner, it is a hexagon and its net is usually depicted as a cross. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges ...
The cubic metre (in Commonwealth English and international spelling as used by the International Bureau of Weights and Measures) or cubic meter (in American English) is the unit of volume in the International System of Units (SI). [1] Its symbol is m3. [1] It is the volume of a cube with edges one metre in length.
Feliks Aleksanders Zemdegs (/ ˈ f ɛ l ɪ k s ˈ z ɛ m d ɛ ɡ z /, Latvian: Fēlikss Zemdegs; born 20 December 1995) is an Australian Rubik's Cube speedsolver.He is one of the only two speedcubers ever to win the World Cube Association World Championship twice (the other being Max Park), winning in 2013 and 2015, and is widely considered the most successful and greatest speedcuber of all time.
The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. It is a simple wire-frame , two dimensional drawing of a cube with no visual cues as to its orientation , so it can be interpreted to have either the lower-left or the upper-right square as its front side.
Begin with a cube. Divide every face of the cube into nine squares, like a Rubik's Cube. This sub-divides the cube into 27 smaller cubes. Remove the smaller cube in the middle of each face, and remove the smaller cube in the center of the more giant cube, leaving 20 smaller cubes. This is a level-1 Menger sponge (resembling a void cube).
Max Park (born November 28, 2001) is a Korean-American Rubik's Cube speedsolver, widely considered as one of the greatest cubers of all time. He is the World Champion of 3×3×3 solving and world record holder for the 3x3x3 single solve at 3.13 seconds set on June 11, 2023. Along with Feliks Zemdegs, he is one of only two speedcubers ever to ...
