Definition – What is the cube of a number?
The “Cube” or “Exponent 3” or “Power of 3” of a number is the number multiplied by itself 3 times. It is written as number3.
Saying “4 cubed” or “4 to the power of 3” or “43” is the same as saying 4 x 4 x 4 = 64.
Saying “10 cubed” or “10 to the exponent 3” or “103” is the same as saying 10 x 10 x 10 = 1,000.
To find a number to a different exponent, use our simple exponent calculaor. To find the number needed to find the cube of a number, use the cubed root.
Formula – How to Calculate a Cubed Number
The cube of a number is found by multiplying that number by itself three times.
number3 = number x number x number
Example
13 = 1 x 1 x 1 = 1
23 = 2 x 2 x 2 = 8
33 = 3 x 3 x 3 = 27
43 = 4 x 4 x 4 = 64
53 = 5 x 5 x 5 = 125
How to type a cubed number
- In Microsoft Word and other Office products, hi-light the “3,” then right-click and select Font to open the font menu. Select “Superscript.”
- In Google Docs and other products, hi-light the “3” you want to have as an exponent. Select “Format” -> “Text” -> “Superscript.”
- In HTML and web documents, surround the exponent 2 with <sup></sup> tags. Write 53 as “5<sup>3</sup>”.
- In LaTeX notation, use the ^ symbol before the exponent. Write 53 as 5^3.
