ANSWER
n = 2.67
Step-by-step explanation
We have to solve the equation:

To do this, we simply have to find the cube root of both sides.
This means that we want to find a number such that multiplying it by itself three times will yield 19.
![\sqrt[3]{n^3}\text{ = }\sqrt[3]{19}](https://img.qammunity.org/2023/formulas/mathematics/college/b181safk1xaotv6a28htrnh9150qks21d3.png)
19 does not have an integer as a cube root, so, solving that with tables/calculator:

That is the value of n.
