Steps to Solve

Understanding Cube Root
The cube root of a number $x$ is the value $y$ such that $y^3 = x$. In this case, we want to find $y$ such that $y^3 = 2$. 
Expressing Mathematically
We express the cube root of 2 mathematically as:
$$ y = \sqrt[3]{2} $$ 
Using a Calculator or Approximation
To find the numerical value of $y$, we can either use a scientific calculator or estimate the value by trial and error.
For instance, try approximate values:
 If $1.2^3 = 1.728$
 If $1.3^3 = 2.197$
This suggests that the cube root of 2 is between 1.2 and 1.3.

Refining the Approximation
Narrow it down:
 If $1.25^3 = 1.953125$ (too low)
 If $1.26^3 = 2.000376$ (too high)
This indicates that the cube root of 2 is approximately 1.25.

Final Value
To get a more precise result, using a calculator gives us:
$$ \sqrt[3]{2} \approx 1.25992 $$
The cube root of 2 is approximately $\sqrt[3]{2} \approx 1.25992$.
More Information
The cube root of a number is important in various fields, such as geometry, physics, and engineering, as it helps in calculating volumes and dimensions. The cube root of 2 is also related to the dimensions of a cube with a volume of 2 cubic units.
Tips
 Misunderstanding cube roots: Some may confuse cube roots with square roots. Remember that cube roots are what you multiply three times (not twice).
 Rounding too early: When estimating or calculating, rounding before reaching the final answer can lead to inaccuracies.
