Assuming the cross-section is a right triangle with legs 5 m and 12 m and the prism length is 16 m:
Area of two triangular bases = 2*(1/2*5*12) = 2*30 = 60 m².
Hypotenuse = sqrt(5^2 + 12^2) = 13 m, so perimeter of triangle = 5 + 12 + 13 = 30 m.
Lateral area = perimeter * length = 30 * 16 = 480 m².
Total surface area = 60 + 480 = 540 m².
Answer: 540 m squared.
Area of two triangular bases = 2*(1/2*5*12) = 2*30 = 60 m².
Hypotenuse = sqrt(5^2 + 12^2) = 13 m, so perimeter of triangle = 5 + 12 + 13 = 30 m.

Total surface area = 60 + 480 = 540 m².
Answer: 540 m squared.
