<h3>
The complete exercise is attached.</h3>
You can observe in the picture attached that the box is a rectangular prism.
The volume of a rectangular prism can be found with this formula:

Where "l" is the length, "w" is the width and "h" is the height.
You know that the lenght of each side of those cubes is 1 centimeter. Therefore, you can multiply the number of cubes on each side of the box by 1 centimeter in order to find the lenght, the width and the height of the box:
Now you can substitute the lenght, the width and the height of the box into the formula shown at the beginning of the explanation:

Finally, evaluating, you get that the volume of the box is:

Answer:
x ≥ 12.5
Step-by-step explanation:
2(x-9) ≥ 17---Use Distributive Property
2x-18 ≥ 17
2x-18+18 ≥ 17+18
2x ≥ 25
2x/2 ≥ 25/2
x ≥ 12.5
I hope this helps!
