The surface area of a rectangular prism (which a sawhorse resembles) can be found using the formula: 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height, respectively.
So, for Kym's sawhorse:
- l = 27 inches
- w = 19 inches
- h = 39 inches
Substituting these values into the formula:
2(27)(19) + 2(27)(39) + 2(19)(39) = 1,494 square inches
Therefore, the total surface area of Kym's sawhorse is 1,494 square inches, rounded to the nearest hundredth.
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)
