What is the surface area of the triangular prism?
A)
175 cm
B)
196 cm?
C)
216 cm?
D)
222 cm?

Answer:
222 cm²
Step-by-step explanation:
Each triangle's area is 6 cm², each side rectangle's area is 75 cm², and the bottom rectangle's area is 60 cm². Since there are two triangles, two side rectangle's, and one bottom rectangle, you would add all of their areas together:
6 + 6 + 75 + 75 + 60 leads you to the answer of 222 cm².
