Asolid has faces that consist of 1 pentagon, 5 congruent equilateral triangles, and 5 congruent squares. the solid has 11 vertices. how many edges does this solid have?

So the solid consist of 1 pentagon, 5 congruent equilateral triangle and 5 congruent squares and has 11 vertices so the number of edges of this solid is 20. I hope you are satisfied with my answer and feel free to ask form more if you have more clarifications.

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
