Asolid has 14 faces and 12 vertices. how many edges does the solid have? . a. 18 edges. b. 20 edges. c. 22 edges. d. 24 edges.

To actually get to the answer for this question, one needs to follow a formula.
Number of faces = 14
Number of vertices = 12
let us assume the number of edges that the solid has = x
Then
Number of faces + (Number of vertices - Number of edges) = 2
14 + (12 - x) = 2
12 - x = 2 - 14
12 - x = - 12
- x = -12 - 12
-x = - 24
x = 24
From the above deduction, we can conclude that the solid has 24 edges. The correct option among all the options that are given in the question is the last option or option "D". I hope the answer helps you.
