Cube Root of 1200
We will learn the cube root concept to use it on other mathematical topics like algebra, mensuration, geometry, trigonometry, etc. So, it is as important as learning square roots. Let us now see how we can obtain the cube root value of 1200, and its examples.
What Is the Cube Root of 1200?
The cube root of 1200 is the value which, when multiplied by itself three times (cubed), gives the original number 1200. The cube root of 1200 is 10.6265856918. The cube root of 1200 is expressed as ∛1200 in radical form, where the “ ∛ ” sign” is called the “radical” sign. In exponential form, it is written as (1200)â…“. If “m” is the cube root of 1200, then, m3=1200. Let us find the value of “m”.
Finding the Cubic Root of 1200
We can find cube roots of 1200 through a method, named as, Halley’s Method. Let us see how it finds the result.
Cubic Root of 1200 By Halley’s Method
Now, what is Halley’s Method? It is an iterative method for finding cube roots of a given number N, such that, x3=N, where this method approximates the value of “x”.
Formula is ∛a≅ x((x3+2a) / (2x3+a)), where
a=given number whose cube root you are going to find
x=integer guess for the cubic root
Let us apply Halley’s method on the given number 1200.
Step 1: Let a=1200. Let us take x as 10, since 103=1000 is the nearest perfect cube which is less than 1200.
Step 2: Apply the formula. ∛1200≅ 10((103+2×1200) / (2(10)3+1200)) = 10.62…
Hence, 10.62… is the approximate cubic root of 1200.
Common Mistakes and How to Avoid Them in the Cube Root of 1200
Understanding common misconceptions or mistakes can make your calculations error free. So let us see how to avoid those from happening.
Mistake 1
For ∛1200, students can make error in the important part of prime factorization.
Prime Factorization is a crucial part in determining cube roots and square roots. So, use the exact prime factors and group (or pair)
Cube Root of 1200 Examples
Problem 1
Find ∛1200/ ∛600
∛1200/ ∛600
= ∛(1200/600)
= ∛2
=1.2599…
Answer: 1.2599…
Explanation
We found that the cubic root of 2 is 1.2599…, upon dividing ∛1200 by ∛600.
Problem 2
The volume of a cube is 1200 cubic centimeters, find the length of one side of the cube.
We know that, (side of a cube)3=Volume of a cube
⇒side of the cube = ∛(Volume of the cube)
⇒side of the cube = ∛1200
⇒ side of the cube = 10.62 cm
Answer: 10.62 cm
Explanation
We applied the formula for finding the volume of a cube, and inverted it to find the measure of one side of the cube.
Problem 3
Subtract ∛1200 - ∛216, ∛1331-∛1200
: ∛1200-∛216
= 10.62–6
= 4.62
∛1331-∛1200
= 11–10.62 = 0.38
Answer: 4.62, 0.38
Explanation
We know that the cubic root of 216 is 6, hence subtracting ∛216 from ∛1200. Applying the same for the next one, we know that the cubic root of 1331 is 11, hence subtracting ∛1200 from ∛1331.
Problem 4
What is ∛(1200²) ?
: ∛(12002) = (1200)2/3
Answer: (1200)2/3
Explanation
Converting the given expression to exponential form.
Problem 5
Find ∛((1200+528)×(1200+997)).
∛((1728)×(2197))
= ∛(1728×2197)
=∛((12)3 × (13)3)
=∛123 × âˆ›133
= 12 × 13
=156
Answer: 156
Explanation
Simplified the expression, and found out the cubic root of the result.

Important Glossaries for Cube Root of 1200
- Cube root properties - The features when cube root is applied to any number. Those are: 1) The cube root of all odd numbers is an odd number. The same applies for even numbers also, that is, the cube of any even number is even.
2) The cube root of a negative number is also negative.
3) If the cube root of a number is a whole number, then that original number is said to be perfect cube
- Irrational Numbers - Numbers which cannot be expressed as m/n form, where m and n are integers and n not equal to 0, are called Irrational numbers.
- Square root -The square root of a number is a number which when multiplied by itself produces the original number, whose square root is to be found out.
- Polynomial - It is an algebraic expression made up of variables like “x” and constants, combined using addition, subtraction, multiplication, or division, where the variables are raised to whole number exponents.
- Approximation - Finding out a value which is near to the correct answer, but not perfectly correct.
