What does cube stand for in math?

Answer 1

A cube is a 3 dimensional shape that has 6 faces, 8 vertices and 12 equal edges and its volume is measured in cubic units.

Also its other meaning is as for example the cube of 3 is 9 and the cube root of 9 is 3

Answer 2

A cube is a mathematical operation.
You take any number, called the root, and multiply it by itself, then multiply the result by the same root number. The result is called the cube of the root number.
eg; 3 x 3 x 3 = 27
27 is the cube of 3
Conversely 3 is the cube root of 27
