Net for the prism will have 3 rectangles with dimensions 5 by 15, 12 by 15 and 13 by 15 and 2 triangles with legs 5 inches and 12 inches.
The correct net is net a.

Surface area = sum of areas of the three rectangles and sum of the two triangles.
SA = (5 x 15) + (12 x 15) + (13 x 15) + (5 x 12) = 75 + 180 + 195 + 60 = 510 square inches.
