Answer:
156 cm^2
Step-by-step explanation:
The surface area of this is the same as the area of the net diagram of this prism.
This net is made up of 3 rectangles and 2 triangles
A triangle would be 3 x 4 ÷ 2 = 6 but we have two of them so together it is 12cm 2 .
The three rectangles all create a bigger rectangle which is (3+4+5 = ) 12cm by 12cm (height) = 144cm 2 .
Altogether it will be 156cm ^2
