    Answer:

    The surface area of the rectangular prism is of 22 square millimeters.

    Step-by-step explanation:

    Surface area of rectangular prism:

    The surface area of a rectangular prism with length l, width w and height h is given by:

    S = 2(lw + lh + wh)

    Length 12 mm, width 3mm and height 5 mm

    This means that l = 12, w = 3, h = 5

    Surface area:

    S = 2(lw + lh + wh) = 2(12(3) + 12(5) + 3(5)) = 2(36 + 60 + 15) = 2(111) = 222

    The surface area of the rectangular prism is of 22 square millimeters.
