So this box will probably be very flat. Draw it out. There would be 4 surfaces with the surface area of 0.25*38. Which equals 9.5. Multiply that by 4 and it's 38. Now take the bigger surfaces. They will be 38 squared, which is 1444. Multiply that by 2, because there are 2 of those surfaces, and you get 2888. To get the total you add them up: 38+2888=2926. So the answer is 2926 meters squared.
P.S: I copied this answer from the answer I gave to someone else, because they asked the same question.
