Total Surface Area = 375
<h2><em><u>
Step-by-step explanation:</u></em></h2>
You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls
<u>Area of the ceiling:</u>
c = length * width
c = 9*6.5 = 58.5
<u>Area of the 2 rectangle walls:</u>
w = 2(length * width)
w = 2(9 * 8)
w = 2(72)
w = 144
<u>Area of floor:</u>
f = 9 * 7.5
f = 67.5
<u>Area of the two trapezoids:</u>
a = 6.5
b = 7.5
h = 7.5
Total Surface Area = c + w + f + t
Total Surface Area = 58.5 + 144 + 67.5 + 105
Total Surface Area = 375
To make your equation easier to graph, you can try simplifying it. Add 6 to both sides.
y-6 = (x+2)
+ 6 + 6
y = x + 8
Then, try plugging in values for x and using that output as your y value. Some coordinates on your graph would be (0, 8), (1, 9), (2, 10), (3, 11), etc.
Hope this helps!
