Choose "Cube a number" to compute n³, or pick a geometry mode to enter any one cube property and get the rest.
Any real number including negatives, fractions, and decimals. Cubing preserves the sign.

3 cubed is 27.

  • Cubing multiplies a number by itself three times: n × n × n, the same as raising it to the power 3.
  • The result is positive because cubing always keeps the sign of the original number.
  • n squared is 9, so multiplying that by 3 once more gives the cube.
  • If n is an edge length, n³ is the volume of a cube with that edge, and 6n² is its total surface area.
