Use the Euler’s Formula (i.e. F +V = E + 2), where F is the total number of Faces in the given solid, V is the total number of the vertices and E is the total number of edges. Count all the faces, vertices and the edges, and to verify the Left-Hand side of Euler’s formula equal to the Right-Hand side of the formula.

Note: Students usually make mistakes while counting the number of edges, and faces of 3-D figures, because edges and faces usually overlap over each other, when we plot a solid on a plane and they seem to us like they are a single edge or a single face.
