Answer 24

Show the Euler's Formula holds true for this polyhedron.

F + V − E = 2

Substitute in for F, V and E using the values from above.

Answer 25

4+4-5?

Answer 26

F + V − E = 2

4 + 4 - 6 = 2

2 = 2


The tetrahedron has 6 edges. I should have checked rather than picking up the 5 earlier in the post. 5 is not the number of edges. It is 6 edges.
