    Answer:

    94 cm²

    Step-by-step explanation:

    The surface area of a rectangular prism is found by finding the surface area of each of the rectangular faces and adding them together.

    l = length = 5 cm

    w = width = 4 cm

    h = height = 3 cm

    SA = 2(lw) + 2(lh) + 2(wh)

    SA = 2(5*4) + 2(5*3) + 2(4*3)

    SA = 2(20) + 2(15) + 2(12)

    SA = 40 + 30 + 24

    SA = 70 + 24

    SA = 94

    The total surface area of the prism is 94 cm²
