Identify the missing cube number in these patterns
Cube numbers
In this topic you are asked to look at a series of numbers from the Cube numbers sequence and fill in the missing number.
Cube numbers are a sequence of numbers that are the result of multiplying a number by itself three times. For example, 2 cubed is written as 2³ and is equal to 2 x 2 x 2 = 8. The first few cube numbers are 1, 8, 27, 64, 125, and so on.
To understand how these numbers work, imagine a cube with sides of length 1. This cube would have a volume of 1 cubic unit. If you increase the side length to 2, the cube would have a volume of 2³ or 8 cubic units. If you increase the side length to 3, the cube would have a volume of 3³ or 27 cubic units.
In general, the nth cube number is found by raising n to the third power. So the formula for the nth cube number is: Cn = n³.
Cube numbers show up in many places in math and science, from calculating the volume of a cube to understanding the properties of certain types of materials.
