    213 m^2

    Step-by-step explanation:

    The surface area for a rectangle prism is given by

    A=2 (wl+hl+hw)

    We know the base is 6 meters by 3.5 m so l = 6 and width = 3.5

    The heigth is 9 m

    A = 2 (6*3.5 + 9 * 6 + 9 * 3.5)

    = 2 * (21 + 54 + 31.5)

    = 2 * (106.5)

    =213 m^2
