The surface area of one rectangular base is given by 17 * 9 = 153 cm^2. Since there are three congruent bases, the total surface area would be 3 * 153 = 459 cm^2.
Therefore, the surface area of the three congruent rectangular bases is 459 cm^2.
Use the image to answer the question.
An illustration shows a 2 D net of a triangular prism with all of its sides open and visible. Dimensions are labeled. The parts that are not visible in 3 D view are marked with dashed lines. It appears as a triangle in the middle attached to a rectangle on each side. The sides of two legs of the triangle are each labeled 9 centimeters. The length and width of the rectangles is 17 centimeters and 9 centimeters respectively. Another triangle of vertical height 7.8 centimeters is attached to one of the rectangles, opposite to the middle triangle.
What is the surface area of the three congruent rectangular bases? Round the answer to the nearest whole number.
