Answer:
B
Step-by-step explanation:
The surface area of the prism is found by finding the area of each surface and adding it together.
The prism has one large rectangle on top that measures 12 by 5 so the area is 60.
The prism also has two equal triangles on the side that measure 3 by 4 so the area of the 2 is 12.
The prism has a rectangle at the back that is 3 by 12 so the area is 36.
Lastly, the prism has a rectangle as its base on the bottom that measures 4 by 12 so the area is 48.
Add the areas together to have the surface area of the prism.
60 + 12 + 36 + 48 = 156
