Cubed Symbol ³

Cubed Symbol is ³, U+00B3 SUPERSCRIPT THREE. It is a compact text character used in simple powers and cubic-unit expressions such as x³, 2³, cm³, and m³. In “2³ = 8,” the superscript means the base is raised to the third power. In “m³,” it forms the unit cubic metre. The character is useful in plain text, but equation editors may use true mathematical superscript layout instead of the precomposed Unicode glyph. Do not confuse ³ with the cube-root sign ∛. A root operation and a third power are inverse concepts, not alternate drawings of the same notation. Also avoid placing an ordinary baseline 3 after a variable when the exponent relationship is required. Copy U+00B3 and keep it immediately after the base or unit. An accessible reading should say “cubed” or “to the third power,” according to context. Product labels and technical tables should define the unit if readers could mistake the exponent. Web content can use literal ³, decimal ³, or hexadecimal ³. This page is limited to the superscript-three character and its compact uses, not golden-ratio notation or every mathematical expression involving a cube. Recopy the sample “Accessible reading: x cubed,” confirm the final text still contains U+00B3, and check that the visible heading names Cubed. This final check protects Cubed Symbol from font substitution, accidental character loss, and intent drift.
