This is level 3; Applying Euler's Formula. You can earn a trophy if you get at least seven questions correct.

One of Euler's Formulas applies to any polyhedron that does not intersect itself. If the number of faces is F, the number of vertices is V and the number of edges is E then:

F + V - E = 2

How many edges does a solid shape have if it has six faces and eight vertices? Correct Wrong
How many edges does a solid shape have if it has four faces and four vertices? Correct Wrong
How many faces does a solid shape have if it has six vertices and twelve edges? Correct Wrong
How many faces does a solid shape have if it has thirty edges and twenty vertices? Correct Wrong
How many vertices does a solid shape have if it has twenty faces and thirty edges? Correct Wrong
A polyhedron has five more edges than vertices. How many faces does it have? Correct Wrong
A polyhedron has twelve more edges than faces. How many vertices does it have? Correct Wrong
How many faces does the polyhedron have that has the same number of faces as vertices and two more edges than vertices? Correct Wrong
A polyhedron has 58 edges and it has the same number of faces as vertices. How many faces does it have? Correct Wrong
A polyhedron has 48 edges and it has the same number of faces as vertices. How many faces does it have? Correct Wrong

Why am I learning this?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?
