Cube Root of 8 is 2. Cube root of a number is a value that, when multiplied by itself twice (or cubed), results in the original number. 8 can be expressed as 2 × 2 × 2, which indicates that when 2 is multiplied by itself twice gives the product as 8. Therefore, the cube root of 8 = ∛(2 × 2 × 2) = 2.
