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 (
) shown to get the sum surface area.
Sides A & D:
![5 * 8 =40](https://img.qammunity.org/2022/formulas/mathematics/high-school/ipbdrt077sp9bsvx11wxfz13dbbg8mb3l0.png)
Sides B & F:
![3 * 8 =24](https://img.qammunity.org/2022/formulas/mathematics/high-school/rxyww5c8iz9cwn3tluyh70v5osvdjfh6y0.png)
Sides C & E:
(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](https://img.qammunity.org/2022/formulas/mathematics/high-school/idzlhdrpqcks4cor3c5xxehu7jkb3u5gpf.png)
Your total surface area would be 158 in.
