I believe the answer would be B. 946.4 square inches is the surface area.
Step-by-step explanation:
So the formula for finding the area for a triangle is base x height divided by 2. The base of the triangles there is 10 inches. The height is 8.66. 10 x 8.66 = 86.6. If you divide this by 2 you will get 43.3 inches as the surface area for each triangle.
There is eight triangles, so 43.3 inches x 8 = 346.4 inches.
Then you do the squares. The sides are 10 inches each. 10 x 10 will get you the area for one square, 100 inches. There are six squares so that equals 600 inches.
You add up the area from the triangles, 346.4, and the area of the squares, 600, to get a total answer of 946.4. inches squared.
Hope this helps!
