I saw the same question a month ago that no one answered on this website and ive been trying to figure it out and cant.

Well, the problem I'm having is that you could theoretically have any dimensions for the opening.

I agree with Orange master, I would think that the dimensions of the rectangular prism would be it's volume which is ,V=9506.25. But dimensions could have another mathematical term use for this informational text.

i did calculate that as the volume, let me try to send the diagram given

Hm,ok but remember there are more than one use of "dimensions" in Math. Try to use the advice wisely.

here is the problem

anonymous · Answer

Okay, because they want the opening to be similar, we need to form a proportion. $$\frac{ 19.5 }{ 39 }=\frac{ 6 }{ 12 }$$Since the proportion is equal, that means the answer is A.
