## How To Find Cube Root Of 3 Digit Number

### How to Solve. First of all check the last digit. In this case it is 3. So, we can predict that the Cubic number will ends with 7 (as 7 3 = 343). Note down 7.

- It can derive the same last digit as 2 and first digit as 1 , which implies that cube root of 1278 is 12, which is not true because technique stands true for perfect cube root only. There is a simple technique to check whether the number is perfect cube or not.
- Let us find the cube of two digit number in the same way as the square of the two digit number. We make use of the identity (a + b) 3 = a 3 + 3a 2 b + 3ab 2 + b 3. Let â€˜aâ€™ be the tens digit of the number and â€˜bâ€™ be the units digit of the number
- How to Solve. First of all check the last digit. In this case it is 4. So, we can predict that the Cubic number will ends with 4 (as 4 3 = 64). Note down 4.
- To find the cube root of a number, you want to find some number that when multiplied by itself twice gives you the original number. For example, if the last digit of the number called out is 3, then the last digit of the cube root is 7 (see the last digit values in the table above). Step 3: Before you try this out on your friends, you should practice until you can calculate the cube root
