What is a cubed root?

The cubed root of a number is the number that would have to be multiplied by itself and by itself again to get the original number.
For example, the cubed root of 27 is 3 as 3 multiplied by 3 multiplied by 3 is 27.
The cubed root of 8,120,601 is 201, as 201 multiplied by 201 multiplied by 201 is 8,120,601.
The cubed root of 8 is 2.8284271247461900976033774484194 as 2.8284271247461900976033774484194 multiplied by 2.8284271247461900976033774484194 is 8.

How to calculate cubed root

Even for perfect cube numbers, cube root can be difficult to calculate by hand.
The most basic techniques involve trial and error.
Example:
Find the cube root of 512
1) Try a number – 5 : 5 times 5 times 5 = 125 (too low)
2) Try another number that is more than 5 – 6: 6 times 6 times 6 = 216 (too low)
3) Try a number that is more than 6 – 10 – 10 times 10 times 10 = 1,000 (too high)
4) Try a number in between 6 and 10 – 8 – 8 times 8 times 8 = 512 (answer)
A cubed root can also calculate as the same number to the exponent 1/3.
3√number = number1/3

What is cubed root used for?

From a practical standpoint, in geometry cubed root can be used to find the length of a side of a cubed when the volume is known.
