The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:

Simplified:

To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.
Answer: 
Step-by-step explanation:
The surface area of a rectangle can be calculated with:

The surface area of a trapezoid can be calculated with:

Calculate the area of the base, wich is a rectangle:

There are two equal rectangles, therefore, multiply the area of any of them by 2:

Calculate the area of the other rectangle:

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

Therefore, the surface area will be the sum of all the areas calculated:

The answer is simply 2x over 5(fraction) +1 so it the first choice
