1. ## Finding Equations

Referring to the figure below (click to enlarge), the length of the green lines are $\displaystyle \sqrt{17}, \sqrt{17}, \sqrt{11}$, and $\displaystyle \sqrt{11}$, how could I find 4 equations in 4 unknowns (not sure that this is the exact amount) for the 4 central angles of the 4 triangles?

No one is responding because your question is vague or incomplete. No one wants to ask you to give more information because it might lead to many more questions. Most of the answerers here are busy people, I guess.

If I may ask, are the dimensions of the box supposed to be given or known? If they are, what are they? You know, the length, width and the height of the box? Or they are supposed to be unknowns?

There are 4 green lines. Which two are sqrt(17) each long? BP and CP?

And, which 4 triangles are they?

4. $\displaystyle CP$ and $\displaystyle DP$ are $\displaystyle \sqrt{17}$. The other two green lengths are $\displaystyle \sqrt{11}$. The four triangles are BAP, APD, DPC, and BPC. If you have any more questions, pls. let me know. - I appreciate your help!

The 3 dimensions of the box?

The box is a cube. We are trying to express the side length of the box in terms of the green lengths (since we know these).
