Answer:
330
Step-by-step explanation:
The prism is a triangular prism
9 * (12 + 5 + 13) + (2 * 30)= 330
30 being the base area
We can break each surface area into it pieces.
For the squares:
9x13=117
9x5=45
9x12=108
For the triangles:
12x5÷2=30
Add all of those together to get the total square area, which is
