Question

What is the approximate surface area of this right prism with triangular bases?

Answer 1

I think it’s 394.2??

Answer 2

394.2 ft

Explanation:

7.8(9) = 70.2 This is the measurement for the two triagular sides

9(12)(3) = 324 This is the measurement for the three rectangular sides

70.2 + 324 = 394.2 Aprox.

I am REALLY sorry if this is wrong...
