What exactly are Cube Numbers?

[henry]

I’ve seen the term “cube number” in my math book. What does it mean and how do I find them?

Cube numbers are the result of multiplying a number by itself three times. For example, 2×2×2=82 × 2 × 2 = 82×2×2=8, so 8 is a cube number. They are also called perfect cubes and follow the form n3n^3n3, where n is any whole number.

Cube numbers are numbers obtained by multiplying a whole number by itself three times. In other words, a cube number is the third power of an integer.

For example:

• ( 1^3 = 1 )
• ( 2^3 = 8 )
• ( 3^3 = 27 )
• ( 4^3 = 64 )

So, 1, 8, 27, 64, etc., are cube numbers.

They’re called cubes because they represent the volume of a cube whose sides are that number of units long.

Cube numbers are the results of multiplying a number by itself three times. For example, 23=82^3 = 823=8 and 33=273^3 = 2733=27. They represent the volume of a cube with sides equal to that number.

Cube numbers are numbers that are obtained by multiplying a whole number by itself three times. For example, ( 2^3 = 2 × 2 × 2 = 8 ). So, 8 is a cube number. In general, if ( n ) is a whole number, then ( n^3 ) is its cube.
