A cube is
a region of space formed by six identical square faces joined along their edges
. Three edges join at each corner to form a vertex. The cube can also be called a regular hexahedron. It is one of the five regular polyhedrons, which are also sometimes referred to as the Platonic solids.
What is a cube in math?
A cube number
is the result when a number has been multiplied by itself twice. The symbol for cubed is
3
. For example, 8 is a cube number because it’s 2 x 2 x 2 (2 multiplied by itself twice); this is also written as 2
3
(“two cubed”). Another example of a cube number is 27 because it’s 3
3
(3 x 3 x 3, or “three cubed”).
