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]
