How to Type Cubed Root on Calculator

Calculating cube roots is essential in mathematics, engineering, and science. This guide explains how to type the cubed root symbol on different calculators and perform cube root calculations accurately.

Keyboard Shortcuts for Cubed Root

Many scientific calculators support keyboard shortcuts for cube roots. Here are the most common methods:

Common Keyboard Shortcuts

Windows Calculator: Press Alt + 2 to type the cube root symbol (∛)
Mac Calculator: Press Option + V to type the cube root symbol
Scientific Calculators: Look for a button labeled "x∛" or "∛x"

If these shortcuts don't work, try using the calculator's function menu or the "2nd" function key to access the cube root operation.

Finding the Cubed Root Button

The location of the cube root button varies by calculator model. Here's how to find it:

Look for a button labeled "x∛" or "∛x" - this is typically found on scientific calculators
If you don't see a dedicated button, check the function (F) or second (2nd) function layer
On some calculators, you may need to press "Shift" or "Alpha" before the root button

Tip

If your calculator doesn't have a cube root button, you can calculate it manually using the formula: ∛a = a^(1/3)

Manual Cube Root Calculation

When a dedicated cube root button isn't available, you can calculate it using exponentiation:

Cube Root Formula

∛a = a^1/3

For example, to find ∛27:

27^1/3 = 3 because 3 × 3 × 3 = 27

This method works on any calculator that supports exponents. Simply enter the number, then press the exponent button (^) and enter 1/3.

Common Uses of Cube Roots

Cube roots have several practical applications:

Volume calculations (finding the side length of a cube when given volume)
Solving cubic equations
Physics calculations involving volume and density
Engineering measurements of cubic dimensions

Cube Root Examples
Number	Cube Root	Verification
8	2	2 × 2 × 2 = 8
27	3	3 × 3 × 3 = 27
64	4	4 × 4 × 4 = 64
125	5	5 × 5 × 5 = 125

Frequently Asked Questions

How do I type the cube root symbol on a calculator?: Use the keyboard shortcuts mentioned above or look for a button labeled "x∛" or "∛x" on your calculator.
What if my calculator doesn't have a cube root button?: You can calculate cube roots manually using the exponent function: enter the number, then press the exponent button and enter 1/3.
Where are cube roots used in real life?: Cube roots are used in volume calculations, solving cubic equations, and various physics and engineering measurements.
How do I calculate the cube root of a negative number?: The cube root of a negative number is negative. For example, ∛(-8) = -2 because (-2) × (-2) × (-2) = -8.
What's the difference between square root and cube root?: A square root finds a number that, when multiplied by itself, gives the original number (√a = a^1/2). A cube root finds a number that, when multiplied by itself three times, gives the original number (∛a = a^1/3).
