How to find cube root when the number us in decimal?
Taking 150 as example
Step 1- Find the integral part
First we have to find out the integral cubes root between which 150 is. At this point you must be aware that 150 lies between 125 (cube of 5) and 216 (cube of 6). So integral part of cube root will be 5.
Step 2- Finding the decimal part of cube root
Divide 150 by square of 5 assume equal to x , i.e. 25. 150/25=6. Now subtract x from integral part (5 in this case) AND DIVIDE BY 3.
6 – 5 = 1 and NOW divided by 3 =>1/3= 0.33.
step 3- Add this decimal number to to the integral cube root i.e. 0.3 + 5 = 5.3. Thus the cube root of 150 is 5.3.Now the actual cube root will be 5.314 but this is an approximation method and results will be always correct to only first decimal place.
hope it help u..
