    Answer:
    144 cm2
    Step-by-step explanation:
    The first step is to solve the surface area of the bottom square (8 times 8=64). The second step is to solbe for the surface area of the four triangles that pop up (l times w all divided by two=Area of a triangle, 5*8/2*4= 5*8*2=40*2=80). Then we add up the sides 64+80=144, which is the answer.
