The total surface area can be calculated by finding the sum of the areas of all the sides.
The area of the top surface = length x width = 27 x 19 = 513 in^2
The area of the bottom surface = length x width = 27 x 19 = 513 in^2
The area of the front surface = height x width = 39 x 19 = 741 in^2
The area of the back surface = height x width = 39 x 19 = 741 in^2
The area of one side surface = height x diagonal side = 39 x 40.14 = 1565.46 in^2 (using Pythagorean theorem)
The area of the other side surface = height x diagonal side = 39 x 40.14 = 1565.46 in^2
Total surface area = 513 + 513 + 741 + 741 + 1565.46 + 1565.46 = 4739.92 in^2
Therefore, the total surface area of Kym's sawhorse is 4739.92 in^2.
Kym’s sawhorse is 39 inches tall, 27 inches long, and 19 inches wide. Its diagonal measurement, or the hypotenuse, is 40.14 inches. What is its total surface area? Round your answer to the nearest hundredth.(1 point)
