A cube of a number is the result of multiplying that number by itself three times (n × n × n = n³). Memorizing the cubes from 1 to 10 is essential for fast mental math in algebra and geometry.
1³ = 1
3³ = 27
5³ = 125
7³ = 343
9³ = 729
| Number (n) | Cube (n³) | Calculation |
|---|---|---|
| 1³ | 1 | 1 × 1 × 1 |
| 2³ | 8 | 2 × 2 × 2 |
| 3³ | 27 | 3 × 3 × 3 |
| 4³ | 64 | 4 × 4 × 4 |
| 5³ | 125 | 5 × 5 × 5 |
| 6³ | 216 | 6 × 6 × 6 |
| 7³ | 343 | 7 × 7 × 7 |
| 8³ | 512 | 8 × 8 × 8 |
| 9³ | 729 | 9 × 9 × 9 |
| 10³ | 1000 | 10 × 10 × 10 |
The cube of 8 (8³) is 8 × 8 × 8 = 512.
The cube of 7 (7³) is 7 × 7 × 7 = 343.
