Answer:

290 in²

Step-by-step explanation:

By inspection of the diagram of the net of the prism (shown in blue on a pirple background), we can see that the area of the 5 x 12 in rectangle is 60 in² and the area of the 5 x 5 square is 25 in².

According to the net, there are four rectangles and two squares.  

Therefore, the total surface area of the prism is:

(4 x 60)+ (2 x 25) = 240 + 50 = 290 in²
