The answer would be C because to find surface area you have to do this: How many faces does the shape have? 6. What are the faces? Front/Back Left/Right Top/Bottom. So then you would find out what Front/Bottom is so you look at the front shape what's the base of it? 14 inches. What's the height of it? 6 inches. 14×6 is 84 now you add 84 and 84 because front ANDROID back so it's 168. Save that number now you do the same to the other sides and add up all the answers at the end to find the surface area. DONT FORGET THIS IS NOT FOR TRIANGULAR PRISMS!
