To get to the answer to this question, one has to follow a formula.Number of faces = 14Number of vertices = 12let us assume the number of edges that the solid has a = xThenNumber of faces + (Number of vertices Number of edges) = 214 + (12 - x) = 212 - x = 2 - 1412 - x = - 12 - x = -12 - 12-x = - 24x = 24From the above deduction, we can conclude that the solid has 24 edges. The correct option among all the options given in the question is the last option or the option "D". I hope the answer helps you.
