How do I dissolve this face into the surrounding face?enter image description here

Whenever I try to dissolve it (Delete > Dissolve Faces) it gives me an error: "Can't create merged face"

    $\begingroup$ Yeah, using complex huge NGons like that is gonna cause lots of problems for modelling, and only create trouble down the road. Learn to use proper tolopoly if you plan to successfully model with meshes. $\endgroup$ – Duarte Farrajota Ramos Feb 20 '17 at 5:07
  • $\begingroup$ So I was trying to create a large maze layout and then extrude it. I created a plane, subdivided it a bunch and carved out my maze, then after merging all my faces together i got stuck with this. Is there a better way to create a maze layout? $\endgroup$ – Sam Feb 20 '17 at 5:29
  • $\begingroup$ If your maze is gonna be "tile based" or follow some sort of "grid layout" best is starting from a large plane subdivided into a regular grid of squares. You can then carve each tile from exactly one square and not end up with a mess like that. $\endgroup$ – Duarte Farrajota Ramos Feb 20 '17 at 5:33

    $\begingroup$ Never merge squares, mesh models should always be based on quads (4 sided faces) as much as possible. Occasional triangles are ok, more than 4-sided faces are to be avoided in final work in most situations. They are Ok as a step towards an end. $\endgroup$ – Duarte Farrajota Ramos Feb 20 '17 at 5:49

    $\begingroup$ It is. It may seem like you are saving geometry with the ngon but in truce you are not. Add a Triangulate modifier to your mesh and you will see what I mean. The geometry is all still there, and will look far worse, not to ention you can't really export ngons anyway. $\endgroup$ – Duarte Farrajota Ramos Feb 20 '17 at 5:56

Although it may seem as though having a complete flat Ngon is preferable, it is far better to keep the most basic shapes and not merge them together.

(Thank you to Duarte Farrajota Ramos for this)
