What is the cube root of 276?

Answer

∛276 ≈
6.5108

Real cube root: the only number whose cube is 276.

≈ — rounded to 4 decimal places. 276 is not the cube of a rational number, so ∛276 is irrational: its decimal expansion never ends and never repeats.

Prime factors
276 = 2 × 2 × 3 × 23 = 2² × 3 × 23
Take out of the root
No prime appears three times, so ∛276 is already in simplest form.
Between cubes
6³ = 216 < 276 < 343 = 7³, so 6 < ∛276 < 7 and ∛276 ≈ 6.5108
