## What is 125 cubed root?

The cubed root of 125 is 5, as 5 x 5 x 5 = 125. Unlike the square root, the cubed root is always positive. The opposite of the cubed root is a cubed (power of 3) calculation. In geometry cubed root can be used to find the length of a side of a cubed when the volume is known.

## How do you calculate square root?

Example: Calculate the square root of 10 ( ) to 2 decimal places.

- Find the two perfect square numbers it lies between. Solution: 3
^{2}= 9 and 4^{2}= 16, so lies between 3 and 4. - Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)
- Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.
