Cube Root Calculator — ∛n
The Cube Root Calculator finds the number which, when multiplied by itself three times, equals your input. The cube root of 27 is 3, because 3 × 3 × 3 = 27. Unlike square roots, cube roots can be found for negative numbers too — the cube root of −8 is −2. Use this for geometry, volume calculations, physics, and algebra.
