Answer:
D.

Step-by-step explanation:
We have been an image of a right prism. We are asked to find the surface area of our given prism.
We will use surface area of prism formula to solve our given problem.
, where,
p = Perimeter of base of prism,
h = Height of prism,
B = Area of base of prism.
Now, we need to find the third side of triangular base of prism using Pythagoras theorem.





Upon substituting our given values in above formula we will get,




Therefore, the surface area of our given prism is 504 square units and option D is the correct choice.
