Have a look at this: So the cube root of â125 is â5. The Perfect Cubes are the cubes of the whole numbers: It is easy to work out the cube root of a perfect cube, but it is really hard to work out other cube roots. Well, 3 Ã 3 Ã 3 = 27 and 4 Ã 4 Ã 4 = 64, so we can guess the answer is between 3 and 4. Let's try 3.5: 3.5 Ã 3.5 Ã 3.5 = 42.875.
