Answer:

158 inches squared

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 (
lw) shown to get the sum surface area.

Sides A & D:
5 * 8 =40

Sides B & F:
3 * 8 =24

Sides C & E:
3 * 5 = 15 (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.


A(40)+D(40)+B(24)+F(24)+C(15)+E(15)\\= 158

Your total surface area would be 158 in.
