Answer:
228 square inches
Explanation:
The two "wings" extend up 4 inches and down 4 inches below the main horizontal set of rectangles. The width of the left column of rectangles is 6 in, so the area of that column is ...
6 in × (4 in + 9 in + 4 in) = 102 in^2
The three rectangles on the right have a total width of ...
(4 in + 6 in + 4 in) = 14 in
and their height is 9 in. The area of those three rectangles is ...
(9 in)(14 in) = 126 in^2
So, the total surface area is ...
102 in^2 +126 in^2 = 228 in^2
The surface area is 228 square inches.
