This table shows the first few whole numbers and their cubes.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| 1 | 8 | 27 | 64 | 125 | 216 | 343 | 512 | 729 | 1000 |
From the table, we can see that the 3√729 = 9 and 3√1,000 = 10.
It also means that we can find an estimate for the cube root of any number between 729 and 1,000.
For example, the 3√800 lies between 9 and 10.
In this activity, we're going to be using known cube roots to estimate the cube roots of more tricky numbers.
Good luck!
