Answer:
1466 cm^2
Step-by-step explanation:
Always remember that it helps a bunch to draw it out to visualize it.
The SA would be the area of all sides added together. The two sides would be 28x9 pieces, another two sides would be 28x13 pieces, and the two bases would be 9x13 pieces. We can make an equation from that info:
[tex]SA = 2(28*9) + 2(28*13)+2(9*13) = 1466 cm^{2}[/tex]
