Faces = 5, edges = 8, vertices = 5
Step-by-step explanation:
Picture a classic pyramid (like the ones in Egypt) - it has a square base, and four walls which join in a point.
Euler formula: F + V = E + 2
If the above answer is correct, then plugging those values into this equation should give us a true statement (5 + 5 = 8 +2) = true
