Answer:
Hopefully you can see the image.
Basically what's going on is the shape is being reflected over this line (x = -1) rather than the origin line.
Hope this helps :)
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:

I think it would be150,000 ml
hope this helps :D
