Answer:

[tex]200cm^{2}[/tex]

Step-by-step explanation:

2 triangles area: A = 2(1/2 b x h)

                           A = 2((6/2) x 4)

                           A = 2(3 x 4)

                           A = 2 x 12

                           A = [tex]24cm^{2}[/tex]

2 rectangles on side: A = 2(l x w)

                                   A = 2(5 x 11)

                                   A = 2 x 55

                                   A = [tex]110cm^{2}[/tex]

rectangle base: A = l x w

                          A = 6 x 11

                          A = [tex]66cm^{2}[/tex]

Total surface area = [tex]24cm^{2}[/tex] + [tex]110cm^{2}[/tex] + [tex]66cm^{2}[/tex]

                               = [tex]200cm^{2}[/tex]
