Meaning & usage

Superscript three raises a number to the third power: 4³ = 4 × 4 × 4 = 64, the volume of a cube — which is exactly where the name comes from. It also labels volume units: litres fit in dm³, concrete is ordered in m³, and engine sizes in cm³ (the 'cc' of motorbikes). Alt+0179 types it on Windows; on any device, copying it from this page is foolproof.

Frequently asked questions

How do I type ³ on a keyboard?

On Windows, hold Alt and type 0179 on the numeric keypad. On many phone keyboards, long-press the 3 key. Or copy it from this page.

Why is the power of 3 called 'cubed'?

Because x³ is the volume of a cube with side x — just as x² is the area of a square, which is why power 2 is called 'squared'.

Why does ³ sometimes show as a box or question mark?

The box (called tofu) means the device or font viewing it has no drawing for U+00B3 (Superscript Three). The character itself is fine — try a different font or a newer device, or use one of the variants on this page.

Is the Cubed Symbol (Superscript Three) free to use?

Yes. ³ is a standard Unicode text character published in the Unicode Character Database. You may use it in personal and commercial documents, designs and products without permission or payment.
