What cube root equals 815? In other words, what number would you take the cube root of to get 815? To solve this problem, we want to find x in the following equation:
∛x = 815
To solve the ∛x = 815 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 815³
x = 815³
Then, we calculate 815³ to get the following answer:
815³ = 815 × 815 × 815
815³ = 541,343,375
∛541,343,375 = 815
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.
