Help plssssssssssssssssssssssssss

Answer 1

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 ($lw$) 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.
