Why cube has the same corner as rectangular prism?

A cube is a specific type of rectangular prism where all its sides are equal in length. Both shapes have eight corners (or vertices) because they are three-dimensional objects with defined lengths, widths, and heights. Each corner in a cube corresponds to a corner in a rectangular prism, as they share the same geometric properties. Thus, the corners of both shapes are located at the same spatial positions relative to their dimensions.
