To calculate the total surface area of the sawhorse, we need to find the areas of all four sides and the two ends.

The area of the two longer sides (27 inches x 39 inches) = 1053 in^2 each
The area of the two shorter sides (19 inches x 39 inches) = 741 in^2 each
The area of the two ends (27 inches x 19 inches) = 513 in^2 each

Total surface area = 2(1053) + 2(741) + 2(513) = 2106 + 1482 + 1026 = 4614 in^2

Therefore, the total surface area of the sawhorse is 4614 in^2.
