1 answer

To find the total surface area of the sawhorse, we need to calculate the surface area of each of the six sides and then add them up.

1. For the bottom rectangular surface: 27 inches long by 19 inches wide = 513 square inches
2. For the top rectangular surface (same as the bottom): 513 square inches
3. For the two longer sides: 39 inches tall by 27 inches long = 1053 square inches each, so a total of 2106 square inches
4. For the two shorter sides (same as the two longer sides): 2106 square inches

Adding them all up: 513 + 513 + 2106 + 2106 = 4238 square inches

Therefore, the total surface area of Kym's sawhorse is approximately 4238 square inches.
