Solution:
<u>First, let's find the surface area of the triangular prism.</u>
- 2(1/2 x 8 x 12) + 2(10 x 6) + (12 x 6) = Surface area of triangular prism
- => (8 x 12) + 2(60) + (72) = Surface area of triangular prism
- => (96) + 120 + 72 = Surface area of triangular prism
- => 96 + 192 = Surface area of triangular prism
- => 288 ft² = Surface area of triangular prism
<u>Now, let's find the surface area of the rectangular prism.</u>
- 2(18 x 9) + 2(6 x 9) + 2(6 x 18)
- => 2(162) + 2(54) + 2(108)
- => 324 + 108 + 216
- => 2(324) = 648 ft²
<u>Now, add both the surface areas to find the surface area of the figure.</u>
- 288 + 648 = Surface area of figure
- => 936 ft² = Surface area of figure
The surface area of the figure is 936 ft².
Answer:
Step-by-step explanation:
7d – 4d – 3d – 5 = 6d
<em>(7d - 4d = 3d)</em>
3d - 3d -5 = 6d
<em>(3d - 3d = 0)</em>
0 - 5 = 6d
-5 = 6d
-5/6 = 6d/6
d =

Simplest fraction form is "3/4"
Correct answers are A and B.
The more precise answers are the numbers which could be rounded to 180. Those are 180.4 and 175.
