I am getting the total (1,073 + 2,726 + 3,478) for surface area of this box as 7,277, not 8,350.

Calculate the surface area of each side of the box. Two sides are each: 29 × 37 × 2 = 1,073 square inches. Two other sides are 29 × 47 × 2 = 2,726 square inches. The last two sides are 37 × 47 × 2 = 3,478 square inches. The sum of the six sides is 8,350.
