To find the total surface area of the sawhorse, we need to find the surface area of each of the six sides: top, bottom, front, back, left side, and right side.
The top and bottom surfaces are in the shape of a rectangle, so the surface area of each is:
39 inches * 19 inches = 741 square inches
And since there are two of them, the total surface area of the top and bottom surfaces is:
2 * 741 square inches = 1482 square inches
The front and back surfaces are in the shape of a rectangle, so the surface area of each is:
39 inches * 27 inches = 1053 square inches
And since there are two of them, the total surface area of the front and back surfaces is:
2 * 1053 square inches = 2106 square inches
The left and right side surfaces are in the shape of a rectangle, so the surface area of each is:
27 inches * 19 inches = 513 square inches
And since there are two of them, the total surface area of the left and right side surfaces is:
2 * 513 square inches = 1026 square inches
Adding all the surface areas together, we get the total surface area:
1482 + 2106 + 1026 = 4614 square inches
Therefore, the total surface area of Kym's sawhorse is 4614 square inches.
