IPA: //ˈhaɪpərˌkjub//
KK: /haɪpərˌkjub/
A geometric shape that exists in four or more dimensions, similar to how a cube exists in three dimensions.
In advanced mathematics, a hypercube is often used to illustrate concepts in higher dimensions.
Hypercube → It is formed from "hyper-" (meaning over or beyond) and "cube" (from Latin "cubus", meaning a three-dimensional geometric figure with six equal square faces). The word "hypercube" refers to a geometric figure that extends beyond the three dimensions of a standard cube into higher dimensions.
Think of 'beyond' ('hyper-') a regular 'cube' — that's why a hypercube represents a shape in dimensions greater than three.
