Kym's sawhorse is 39 inches tall, 27 inches long, and 19 inches wide. It's diagonal measurement or the hypotenuse is 40.14 inches. What is its total surface area? Round your answer to the nearest hundredth.
To find the total surface area of the sawhorse, we need to calculate the area of each of its six faces.
1. The top surface area is 27 inches long by 19 inches wide = 513 square inches
2. The bottom surface area is also 27 inches by 19 inches = 513 square inches
3. The front face is 39 inches tall by 19 inches wide = 741 square inches
4. The back face is also 39 inches tall by 19 inches wide = 741 square inches
5. One of the side faces is 27 inches long by 39 inches tall = 1053 square inches
6. The other side face is the same = 1053 square inches
Adding up the areas of all six faces:
513 + 513 + 741 + 741 + 1053 + 1053 = 4614 square inches
Therefore, the total surface area of Kym's sawhorse is 4614 square inches.
