50% off
Step-by-step explanation:
Answer: The second option.
Step-by-step explanation:
1. Calculate the first volume assuming that the figure is completed (with no missing part). Therefore, you must apply the formula for calculate the volume of a square prism:

Where s is the side of the base and h is the height.
2. Then:

4. The volume of the missing part is calculated with the formula of a rectangular prism:

Where l is the lenght, w is the width and h is the height. Then:

5. Therefore, you must subtract both volumes to obtained the volume of the figure:

2((x+2)(x+2)}-4=28
2{x^2 + 4x + 4}-4=28
2x^2 +4x=28
2(x^2+2x)=28
x^2+2x=28/2
x^2+2x=14
