What is a Cube Root?
The cube root of a number is a number which, when multiplied three times, gives the original number. It is denoted by ∛.
For example:
∛8 = 2, as 2 * 2 * 2 = 8
∛27 = 3, as 3 * 3 * 3 = 27
∛125 = 5, as 5 * 5 * 5 = 125
Mathematically, if x³ = y, then ∛y = x.
The cube root is a significant concept in algebra, and it is used in many calculations in mathematics and science.

These are some of the most important features of an online cube root calculator that make it very useful for both beginners and experts.
How to Use a Cube Root Calculator
It is extremely easy to use the cube root calculator. You can do this by following the steps below:
- Enter the number for which you want to find the cube root
- Specify the decimal precision you want
- Click on the “Calculate” button or press Enter
- View the result immediately
You can also clear the input fields and make multiple calculations.
Cube Root vs Square Root
Most often, people get confused between cube roots and square roots. However, these two are very different from each other.
Square Root (√)
- This is the number that is multiplied by itself once.
- Example: √9 = 3
- This is only possible for non-negative numbers in the real number system.
Cube Root (∛)
- This is the number that is multiplied by itself three times.
- Example: ∛27 = 3
- This can be done for positive or negative numbers.
For example:
- √16 = 4
- ∛16 = 2.52
The growth of cube roots is slower compared to square roots.
Can Cube Roots Be Negative?
Yes, cube roots of negative numbers do exist. This is one of the biggest differences between square roots and cube roots.
Example:
∛(-8) = -2 because (-2 × -2 × -2 = -8)
∛(-27) = -3
Perfect Cubes You Should Know
Memorizing the perfect cube values will help you to quickly recall the cube root values:
1³ = 1 ∛1 = 1
2³ = 8 ∛8 = 2
3³ = 27 ∛27 = 3
4³ = 64 ∛64 = 4
5³ = 125 ∛125 = 5
6³ = 216 ∛216 = 6
7³ = 343 ∛343 = 7
8³ = 512 ∛512 = 8
9³ = 729 ∛729 = 9
10³ = 1000 ∛1000 = 10
This will help you with quick calculations.
How to Calculate Cube Roots Manually
Although the use of a calculator is the most efficient way, estimation of cube roots can also be done by hand.
Problem: Calculate ∛50
List the perfect cubes:
3³ = 27
4³ = 64
Hence, ∛50 is between 3 and 4
Estimate the cube root:
3.6³ = 46.656
3.7³ = 50.653
Make a precise estimation:
∛50 ≈ 3.68
Real-Life Applications of Cube Roots
Cube roots do not remain confined to theoretical calculations. They find their applications in many fields:
- Volume Calculations
