Hi
Use Euler's formula for this for a 3D figure. F + V = E + 2, where F is the number of faces, V is the number of vertices, E is the number of edges, +2! You have enough info to fill in the formula to find that the number of vertices is 6.

Determine any equation where n = 6
![n = 6](https://tex.z-dn.net/?f=n%20%3D%206)
Add n to both sides
![n + n = 6 + n](https://tex.z-dn.net/?f=n%20%2B%20n%20%3D%206%20%2B%20n)
<em></em>
<em> ----- This is 1 equation</em>
![n = 6](https://tex.z-dn.net/?f=n%20%3D%206)
Multiply both sides by n
![n * n = 6 * n](https://tex.z-dn.net/?f=n%20%2A%20n%20%3D%206%20%2A%20n)
<em></em>
<em> ----- This is another</em>
<em></em>
![n = 6](https://tex.z-dn.net/?f=n%20%3D%206)
Add 5n to both sides
![n + 5n = 6 + 5n](https://tex.z-dn.net/?f=n%20%2B%205n%20%3D%206%20%2B%205n)
<em></em>
<em> ---- This is another</em>
Subtract 10 from both sides
![6n - 10 = 6 - 10 + 5n](https://tex.z-dn.net/?f=6n%20-%2010%20%3D%206%20-%2010%20%2B%205n)
![6n - 10 = -4 + 5n](https://tex.z-dn.net/?f=6n%20-%2010%20%3D%20-4%20%2B%205n)
