Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area ([tex]lw[/tex]):
[tex]7.21*14=100.94[/tex]
The triangle's area ([tex]\frac{1}{2}bh[/tex]):
[tex]\frac{1}{2} (6)(8)[/tex]
[tex]\frac{1}{2} (48)=24[/tex]
Now add up all the sides. (3 Rectangles, 2 Triangles.)
[tex]100.94 + 100.94 + 100.94 + 24 + 24[/tex]
[tex]=350.82[/tex]
The total surface area is 350.82 cm squared.
