    Mass of aluminium foil = 387.57_g

    Explanation:

    density of aluminium foil 2.70 g/cm³,

    1_yd = 91.44_cm

    1_in = 2.54_cm

    Length of aluminum foil = 63.2_yd = 5779.008_cm

    Width of aluminium foil = 11 in = 27.94_cm

    Thickness of aluminium foil = 0.00035_in. = 0.000889_cm

    Volume of aluminium foil = length * width * thickness = 5779.008_cm * 27.94_cm * 0.000889_cm = 143.54_cm^3

    Mass of aluminium foil = (volume of aluminium foil) * (density of aluminium foil) = 143.54_cm³ * 2.70 g/cm³ = 387.57_g
