Cube Root of 962
In this article we will look at the cube root of the number 962 and show you how to calculate it and determine if it is a perfect cube or not.
What is a cube root?
The cube root of 962 is another number that when multiplied by itself twice, would be exactly equal to 962.
We would normally express this problem in mathematical form by using the cube root symbol with the number alongside it:
You might notice that this symbol is very similar to the square root symbol. The only difference is the number, called the index, above the symbol, which lets us know this a cube root calculation.
To recap: the
√ symbol itself is called the radical symbol, the number above it is called the index, and the actual number, 962, is called the radicand.
The basic formula we use to calculate a cube number from the result is a number which we'll call
n in this example, that when multiplied by itself twice, is equal to 962:
When we use
∛962, the actual math calculation we perform is
962⅓. This means you can use that formula in Excel, Google Sheets, or Mac Numbers to calculate the cube root:
We calculated the cubic root of 962 for this article using a scientific calculator. If you have one yourself, you can confirm the results by typing the following into the calculator:
- Type the number: 962
- Press the
You should now be able to confirm that the cube root of 962 is:
Is 962 a perfect cube number?
Whenever the cube root of a given number is a whole number without any fractional or decimal part, we call this a perfect cube.
These are important for a lot of different math functions and can be used in simpler settings like carpenty and room design all the way through to more advanced calculations in physics and astronomy.
For the number 962 we have already calculated the answer of
9.8716941345623 using a scientific calculator and since this is not a whole number, we also know that 962 is not a perfect cube number.
We have a list of perfect cubes article which covers the first 500 perfect cube numbers for you.
Is the cube root of 962 a rational or irrational number?
This is a commonly asked question and the answer to whether the cube root of 962 is rational or irrational is always the same as if it is a perfect cube.
Remember that a rational number can be written as a fraction, while irrational numbers can't.
So, if a number is a perfect cube, then it's a rational number, but if it is not a perfect cube then it is an irrational number.
We just confirmed that 962 is not a rational number then, because we know it is not a perfect cube number.
Rounding the cube root of 962
There might be occasions when you need to round the result of a cube root calculation down to a specific number of decimal places. Below, we show an example of a few of these to specific decimal places that show up in exam questions:
10th: ∛962 = 9.9
100th: ∛962 = 9.87
1000th: ∛962 = 9.872
Simplifying the cube root of 962
Sometimes, the radicand can be simplified and made smaller. If that is possible, we call it the cube root of 962 in its simplest form.
The cube root of 962 cannot be simplified down any further in this example, so there are no further calculations to be made.
