SOLUTION:
Case: Euler's formula
Given:
Faces= 20
Vertices =12
Euler's formula: F + V = E + 2
Required: To find the number of Edges
Method:
Step 1: Recreate the formula to isolate E
F + V = E + 2
E = F+V - 2
Step 2: Plug in the value of the variables
E = F+V - 2
E= 20 + 12 - 2
E = 30
Step 3:
The value of E is 30
Final answer:
The Polyhedron has 30 edges
