The surface area of the pentagonal prism is 648 square inches.
Step-by-step explanation:
Step 1:
The surface area of a shape is the sum of all the areas of all the external surfaces.
The pentagonal prism has a total of 7 sides i.e. 2 pentagonal sides and 5 rectangular sides.
The total surface area of the prism is the sum of the individual areas of the 7 sides.
Step 2:
The area of the 2 pentagonal sides 
square inches.
The area of each rectangular side is 80 square inches. So
The area of 5 rectangular sides 
square inches.
The total surface area of the prism 
square inches.
The surface area of the pentagonal prism is 648 square inches.

Answer:
-5/12 or .416
Step-by-step explanation:
Convert 2 1/2 to 5/2 and 1 3/4 to 7/4 then just solve from there!
16 boards that are 5.7 inches wide each make a total of 91.20 inches.
16
<u>x 5.7
</u> 112
<u>+800
</u> 91.2 inches
Since the deck itself is 94.45 inches deep, we can subtract 91.2 from the number:
94.45
<u>-91.20</u>
3.25 inches.
Finally, we divide 3.25 by 15, since that's the amount of spaces we want and they have to be equal:
3.25/15= .21667
We'll round that to two numbers, so we'll end up with .22.
Your final answer is .22 inches wide for each space.
