? were you confused by the cube? squared which is usually denoted as x^2 x*x cube is denoted as x^3 or x*x*x sometimes they say x raised to the 3rd power etc.

The volume of a cube is $$\huge x^3$$

Just like the area of a square is $$\huge x^2$$
OpenStudy (rhystic):
oh nvm
OpenStudy (skullpatrol):
That's why they say "cubed" or "squared".

You will also hear 8 to the second power or the second power of 8.
The power of a number is the product when a number is multiplied by itself a given number of times:
$$\huge 4∙4∙4$$
$$\huge\text{or}$$
$$\huge 4^3$$
is the third power of 4.
