To explain the cube root a little more, the cube root of the number 800 is a number (which we call n) that when multiplied by itself twice is equal to 800:

∛800 is the same as 800⅓ and so if you are solving a problem in a spreadsheet like Excel, Numbers, or Google Sheets, you can use =800^(1/3) to calculate the cube root.

If we look at the number 800, we know that the cube root is 9.2831776672256, and since this is not a whole number, we also know that 800 is not a perfect cube.

If you want to learn more about perfect cube numbers we have a list of perfect cubes which covers the first 500 perfect cube numbers.

Another common question you might find when working with the roots of a number like 800 is whether the given number is rational or irrational. Rational numbers can be written as a fraction and irrational numbers can't.

It is possible to simplify the cube root of 800 if the radicand can be made smaller. When that is possible, it is called the cube root of 800 in its simplest radical form.

We have listed a selection of completely random numbers that you can click through and follow the information on calculating the cubic root of that number to help you understand number roots.

When the cube root of a given number is a whole number, this is called a perfect cube. Perfect cubes are important for many mathematical functions and are used in everything from carpentry through to more advanced topics like physics and astronomy.

The quickest way to check if a number is rational or irrational is to determine if it is a perfect cube. If it is, then it's a rational number, but if it is not a perfect cube then it is an irrational number.

So, the √ is called the radical symbol, the little 3 above it is the index (which means multiply by itself two more times), and the number, 800, is called the radicand.

Sometimes when you work with the cube root of 800 you might need to round the answer down to a specific number of decimal places:

We would show this in mathematical form with the cube root symbol, which is similar to the radical symbol (√) used in a square root, but which also has the number 3 above the symbol (this number is called the index):
