Answer:
6 faces does it have
Step-by-step explanation:
In any convex polyhedron:
let v be the number vertices , e is the number of edges and f is the number of faces then;
\(v+f-2 = e\) ....[1]
As per the statement:
If a figure has eight vertices and 12 edges
⇒v = 8 and e = 12
Substitute in [1] to solve for f, we have;
\(8+f-2 = 12\)
⇒\(6+f = 12\)
Subtract 6 from both sides we have;
f = 6
Therefore, 6 faces does it have
