Determining angles for sub box

[Headbanger 10+ year member]

How do you calculate what angles you need to cut the MDF for a wedge shaped box? For instance I have a box planned out with the outside dimensions of:

Depth 1: 7"

Depth 2: 12"

Height: 12"

Width: 14"

What I need to know is what angles to cut the sloped parts of the box so the edges mate up flush.

I believe we call that a protractor, unless you're talking about something else.

I was thinking it would be cool to have the box start out as a quasi-dodecahedron, then morph into a rhombic triacontahedron, from front to back, all while only using compound angles. Just draw it out on a napkin with a pink crayon, then cut it out with a dremmel and some lip balm.

Glad I could help.
