"Three cubed" or "Three raised to the third power"

Explanation:

The analog of a square in different dimensions is:

0 - a point

1 - a line segment

2 - a square

3 - a cube

The measure (length, area, volume, etc.) of these analogs for an n-dimensional shape of side a is:

0 dimensions (point): a0=1 - one object (points only have count, no dimension).

1 dimension (line segment): a1=a - length a

2 dimensions (square) a2 - area a squared

3 dimensions (cube) a3 - volume a cubed.

So in our example 33=3×3×3=27 is the volume of a cube of side 3.
