Answer:
158 inches squared
Step-by-step explanation:
I am calling them Inches instead of centimeters because the image only shows inches as the unit.
To find the surface area, you need to add up all the rectangles' areas ([tex]lw[/tex]) shown to get the sum surface area.
Sides A & D: [tex]5 * 8 =40[/tex]
Sides B & F: [tex]3 * 8 =24[/tex]
Sides C & E: [tex]3 * 5 = 15[/tex] (You get 5 inches from the edges, if you fold it into a rectangular prism, the side would have dimensions of 3x5.)
Then, you add all of the sides together.
[tex]A(40)+D(40)+B(24)+F(24)+C(15)+E(15)\\= 158[/tex]
Your total surface area would be 158 in.
