    Answer:

    The surface area of this rectangular prism is 150.5 inches^{2}.

    Step-by-step explanation:

    The formula for finding the surface area of a rectangular prism is this :

    A=2(wl + hl + hw)

    l = 3.5, w = 9, h = 3.5

    Now we substitute those values in and solve for A.

    A = 2 · ( 9 · 3.5 + 3.5 · 3.5 + 3.5 ·9) = 150.5

    The surface area of this rectangular prism is 150.5 inches^{2}.

    Hope this helps, please mark brainliest. Have a great day!
