Unit hypercube
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.cite-ref-pcm-1-1[1]cite-ref-cbm-2-1[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].cite-ref-pcm-1-2[1]
The length of the longest diagonal of a unit hypercube of n dimensions is n {\displaystyle {\sqrt {n}}} , the square root of n and the (Euclidean) length of the vector (1,1,1,....1,1) in n-dimensional space.cite-ref-cbm-2-2[2]
