Cube Root of 373

In math, the cube root of a number like 373 is a number that, when multiplied by itself two times, is equal to 373.

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):

∛373

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, 373, is called the radicand.

To explain the cube root a little more, the cube root of the number 373 is a number (which we call n) that when multiplied by itself twice is equal to 373:

n × n × n = 373

∛373 is the same as 373 and so if you are solving a problem in a spreadsheet like Excel, Numbers, or Google Sheets, you can use =373^(1/3) to calculate the cube root.

For the purposes of this article, we'll use a scientific calculator to work out the cubic root by typing the number 373 and pressing the [∛x] button, to give the following answer:

∛373 ≈ 7.198404996482

Is 373 a Perfect Cube?

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.

If we look at the number 373, we know that the cube root is 7.198404996482, and since this is not a whole number, we also know that 373 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.

Is the Cube Root of 373 a Rational or Irrational Number?

Another common question you might find when working with the roots of a number like 373 is whether the given number is rational or irrational. Rational numbers can be written as a fraction and irrational numbers can't.

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.

We already know that 373 is not a rational number then, because we know it is not a perfect cube.

Rounding the Cube Root of 373

Sometimes when you work with the cube root of 373 you might need to round the answer down to a specific number of decimal places:

10th: ∛373 = 7.2

100th: ∛373 = 7.20

1000th: ∛373 = 7.198

Simplifying the Cube Root of 373

It is possible to simplify the cube root of 373 if the radicand can be made smaller. When that is possible, it is called the cube root of 373 in its simplest radical form.

In this example, the cube root of 373 cannot be simplified down any further.
