Answer:


\text{D. }464\:\mathrm{ft^2}

Explanation:

The surface area of the prism consists of four rectangles and two trapezoids. The sum of the areas of these polygons will give the total surface area of the prism:

Rectangle 1 (top base):
12\cdot 14=168

Rectangle 2 (bottom base):
6\cdot 14 = 84

Trapezoids 1 and 2 (lateral):
2\cdot 9 \cdot 4=72

Rectangles 3 and 4 (lateral):
2\cdot 14\cdot 5=140

Thus the total surface area is equal to


168+84+72+140=\boxed{\text{D. }464\:\mathrm{ft^2}}
