What is a Cube Number?

A cube number (also called a perfect cube) is the result of multiplying an integer by itself three times. In mathematical notation, the cube of a number n is written as n³ (n cubed), which equals n × n × n.

The term "cube" comes from geometry: a cube with side length n has a volume of n³ cubic units. This is why cubing a number is equivalent to calculating the volume of a cube with that side length.

The Formula for Cube Numbers

The formula for calculating the nth cube number is straightforward:

Where n is any positive integer. For example:

• The 6th cube number: 6³ = 6 × 6 × 6 = 216
• The 10th cube number: 10³ = 10 × 10 × 10 = 1,000
• The 15th cube number: 15³ = 15 × 15 × 15 = 3,375

The First 10 Cube Numbers

The first 10 cube numbers are: 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1,000. Here is the complete breakdown:

• 1³ = 1: The smallest cube number
• 2³ = 8: The first even cube
• 3³ = 27: The first odd cube greater than 1
• 4³ = 64: Also 4² squared (2&sup6;)
• 5³ = 125: Ends in 5 (all cubes of numbers ending in 5 end in 5)
• 6³ = 216: The smallest cube that is the sum of three cubes (216 = 3³ + 4³ + 5³)
• 7³ = 343: A palindrome when cubed from a prime
• 8³ = 512: Also 2&sup9;
• 9³ = 729: Also 3&sup6; and 27²
• 10³ = 1,000: The first four-digit cube

Sum of Cube Numbers Formula

One of the most beautiful results in mathematics is that the sum of the first n cubes equals the square of the sum of the first n natural numbers:

This can also be written as: The sum of the first n cubes = (nth triangular number)²

For example, the sum of the first 4 cubes:

• 1³ + 2³ + 3³ + 4³ = 1 + 8 + 27 + 64 = 100
• Using the formula: [4(4+1)/2]² = [4 × 5/2]² = 10² = 100

Properties of Cube Numbers

Parity Patterns

• The cube of an even number is always even
• The cube of an odd number is always odd
• Cubes alternate: odd, even, odd, even... following the base numbers

Last Digit Patterns

Cube numbers have interesting patterns in their last digits:

• Numbers ending in 0, 1, 4, 5, 6, or 9 have cubes ending in the same digit
• Numbers ending in 2 have cubes ending in 8, and vice versa
• Numbers ending in 3 have cubes ending in 7, and vice versa

Difference Patterns

The differences between consecutive cubes follow a pattern:

• 2³ - 1³ = 8 - 1 = 7
• 3³ - 2³ = 27 - 8 = 19
• 4³ - 3³ = 64 - 27 = 37

The pattern: (n+1)³ - n³ = 3n² + 3n + 1

Applications of Cube Numbers

• Geometry: Calculating volumes of cubes and cube-shaped objects
• Physics: Understanding cubic relationships in nature (inverse cube law)
• Computer Science: Algorithm complexity analysis (O(n³))
• Number Theory: Studying perfect cubes and sums of cubes
• Cryptography: Some encryption methods use cube operations

Famous Problems Involving Cubes

Fermat-Wiles Theorem (Fermat's Last Theorem)

There are no three positive integers a, b, and c that satisfy a³ + b³ = c³. This was proven by Andrew Wiles in 1995.

Taxicab Numbers

1729 is famous as the smallest number expressible as the sum of two cubes in two different ways: 1729 = 1³ + 12³ = 9³ + 10³. This is known as the Hardy-Ramanujan number.

Frequently Asked Questions

What is a cube number?

A cube number (also called a perfect cube) is the result of multiplying an integer by itself three times. For example, 27 is a cube number because 27 = 3 × 3 × 3 = 3³. The sequence of cube numbers starts with 1, 8, 27, 64, 125, 216, and so on.

What is the formula for cube numbers?

The formula for the nth cube number is n³ (n cubed), which equals n × n × n. For example, the 5th cube number is 5³ = 5 × 5 × 5 = 125. This formula works for any positive integer n.

What are the first 10 cube numbers?

The first 10 cube numbers are: 1 (1³), 8 (2³), 27 (3³), 64 (4³), 125 (5³), 216 (6³), 343 (7³), 512 (8³), 729 (9³), and 1000 (10³).

How can I check if a number is a perfect cube?

To check if a number is a perfect cube, find its cube root and see if it is a whole number. For example, the cube root of 64 is 4 (since 4³ = 64), so 64 is a perfect cube. You can also use our Perfect Cube Checker feature above.

What is the sum formula for cube numbers?

The sum of the first n cube numbers equals [n(n+1)/2]². This is remarkably the square of the nth triangular number. For example, 1³ + 2³ + 3³ + 4³ = 1 + 8 + 27 + 64 = 100 = (4×5/2)² = 10².
