How to Cube A Number
To cube a number, just use it in a multiplication 3 times ...
Example: What is 3 Cubed?
3 Cubed = cube 3x3x3
= 3 × 3 × 3 = 27
Note: we write "3 Cubed" as 33
(the little 3 means the number appears three times in multiplying)
Cubes From 03 to 63
0 cubed = 03 = 0 × 0 × 0 = 0
1 cubed = 13 = 1 × 1 × 1 = 1
2 cubed = 23 = 2 × 2 × 2 = 8
3 cubed = 33 = 3 × 3 × 3 = 27
4 cubed = 43 = 4 × 4 × 4 = 64
5 cubed = 53 = 5 × 5 × 5 = 125
6 cubed = 63 = 6 × 6 × 6 = 216
Cube Root
A cube root goes the other direction:
3 cubed is 27, so the cube root of 27 is 3
3 cube root direction 27
The cube root of a number is ...
... a special value that when cubed gives the original number.
The cube root of 27 is ...
... 3, because when 3 is cubed you get 27.
tree root
Note: When you see "root" think
"I know the tree, but what is the root that produced it?"
In this case the tree is "27", and the cube root is "3".

Example: What is the Cube root of 125?
Well, we just happen to know that 125 = 5 × 5 × 5 (if you use 5 three times in a multiplication you will get 125) ...
