A regular polyhedron has 28 edges 25 faces how many vertices ?

OpenStudy (perl):

there is a formula, eulers theorem

OpenStudy (austinl):

Yep, I am looking and it doesn't fit any named figures either. Closest one I can find is Great icosahedron.

OpenStudy (perl):

Eulers theorem For any polyhedron that doesn't intersect itself, the Number of Faces plus the Number of Vertices (corner points) minus the Number of Edges always equals 2 This can be written: F + V - E = 2

OpenStudy (anonymous):

ayee ok then but can yall givee me a random number that could be it ?

OpenStudy (perl):

25 + V - 28 = 2

OpenStudy (perl):

V = 5

OpenStudy (anonymous):

nun of the answers have that number they have 14 18 15 or 16

OpenStudy (perl):

something is wrong with this formula , or your question

OpenStudy (perl):

you sure its not 15 faces?
