What is a Cube Root?
The cube root of a number is the value that, when multiplied by itself three times, gives you that number back.
In simple terms:
The cube root of a number “a” is a number “b” such that b × b × b = a.
For example:
The cube root of 8 is 2 because 2 × 2 × 2 = 8.
The cube root of 125 is 5 because 5 × 5 × 5 = 125.
In other words, cube roots “reverse” the process of cubing a number. If you cube 3 to get 27, taking the cube root of 27 brings you back to 3.
Meaning of the Cube Root Symbol and Definition
The cube root symbol is written as ∛, and it represents the operation of finding the cube root of a number. It works just like the square root symbol (√), except it applies to three factors instead of two.
In mathematical terms:
∛x = x¹/³
The small number “3” next to the root sign indicates that it’s a cube root, not a square root.
Definition:
The cube root of a number is the value that, when cubed, gives the original number.
For example, since 4 × 4 × 4 = 64, we can say that ∛64 = 4.
To understand the cube root definition better, let’s break down some important terms:
Cube (or Cubing): Multiplying a number by itself three times. Example: 3³ = 27.
Root: The inverse of an exponent.
Exponent (Power): Indicates how many times a number is multiplied by itself. Example: 2³.
Understanding these words helps explain how cube roots simplify complex relationships between numbers.
Example of Cube Root:
Imagine you have a cube-shaped container with a volume of 27 cubic meters. You want to find the length of one side.
Side = ∛Volume → ∛27 = 3 meters.
This idea is used in architecture, construction, 3D design, packaging, and more.
Finding cube roots like 8, 27, or 64 is easy because they’re perfect cubes. But numbers like ∛10 or ∛50 give infinite decimals (irrational numbers).
That’s why the Cube Root Calculator on Hive Calculator is so useful. It computes cube roots instantly for integers, fractions, decimals, or negative numbers.

Why Use the Cube Root Calculator
Practical Uses of Cube Roots
Perfect Cubes and Negative Cube Roots
A perfect cube is a number that can be expressed as the cube of a whole number.
1³ = 1, 2³ = 8, 3³ = 27, 4³ = 64, 5³ = 125.
Unlike square roots, cube roots handle negative numbers:
∛(-8) = -2 because (-2) × (-2) × (-2) = -8.
When to Use Cube Roots
Cube roots are useful when:
• Finding the edge of a cube from its volume • Scaling 3D objects • Determining growth across three equal periods • Solving cubic equations

Frequently Asked Questions (FAQs)
A cube root is the number that, when multiplied by itself three times, gives the original number. In simple terms, it’s the inverse of cubing a number.
For example, since 4 × 4 × 4 = 64, the cube root of 64 is 4.
Cube roots are represented by the symbol ∛ and can be used for both positive and negative numbers. For instance, ∛(-8) = -2 because (-2) × (-2) × (-2) = -8.
Using the Cube Root Calculator is very simple.
Enter the number for which you want to find the cube root.
Click on the “Calculate” button.
The cube root will appear instantly with up to six decimal places of accuracy.
If you want to start over, just click “Clear” and enter a new number. The tool works perfectly for integers, decimals, and even negative numbers.
Perfect cubes are numbers that can be expressed as the cube of an integer. For example, 1, 8, 27, 64, and 125 are all perfect cubes because:
When you take the cube root of a perfect cube, you always get a whole number.
For instance, ∛125 = 5.
Non-perfect cubes like 10 or 50 will give decimal or irrational results.
Cube roots are used in many practical areas beyond just mathematics. In geometry, they help find the side length of a cube when its volume is known. In engineering and architecture, cube roots are used to calculate measurements and material proportions in three-dimensional spaces. They also appear in physics when dealing with density and volume, in computer graphics for 3D modeling, and even in finance when analyzing growth rates over three periods.
