What cube root equals 120? In other words, what number would you take the cube root of to get 120? To solve this problem, we want to find x in the following equation:
∛x = 120
To solve the ∛x = 120 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 120³
x = 120³
Then, we calculate 120³ to get the following answer:
120³ = 120 × 120 × 120
120³ = 1,728,000
∛1,728,000 = 120
We made the equation above so you will get a full understanding of how to solve problems like this. In the future, note that you can solve all similar problems by simply multiplying the number by itself twice to get the answer.
