This table shows the first few whole numbers and their cubes.
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.
