The test can be found on this website.
This is the ONLY problem I can not figure out. It gives "EQUILATERAL AND CONGRUENT ISOSCELES TRIANGLES."
I can NOT wrap my mind around this problem. It seems to me like the base of the "pyramid" is a parallelogram (probably a rectangle), and the answer should therefore be 719 as well. I can't get any way of figuring 663, as the answer says.
If you have any advice here, that'd be great. Thanks in advance.

Nope, I just can NOT see what you're talking about. I don't see the correct triangles, distances, or something.
Thanks tho. It's still a pyramid in my book. And I can't do anything to change that. :P
