132 $cm^{2}$
Given the bases of the hexagonal prism in Exercise 1 has an area of 12 $cm^{2}$ each lateral face has an area of 18 $cm^{2}$ To find the the total (surface) area of the prism. Using Theorem 9.1.2 The total area of any prism with lateral area L and base area B is given by T = L + 2B Therefore hexagonal has six lateral faces and two bases T = 6(L) + 2B = 6(18) + 2(12) =108 + 24 =132 $cm^{2}$
