    The length of foil will be 8107.81 cm or 81.7081 m.

    Explanation:

    Given dа ta:

    Width of roll of foil = 302 mm

    Height or thickness = 0.018 mm

    Density of foil = 2.7 g/cm³

    Mass of foil = 1.19 Kg

    Length of foil = ?

    Solution:

    d = m / v

    v = length (l) * width (w) * height (h)

    First of we will convert the Kg into gram and mm into cm.

    one Kg = 1000 g

    1.19 * 1000 = 1190 g

    one cm = 10 mm

    302 / 10 = 30.2 cm

    0.018 / 10 = 0.0018 cm

    Now we will put the values in formula:

    d = m / l * h * w

    l = m / d * h * w

    l = 1190 g / 2.7 g/cm³ * 30.2 cm * 0.0018 cm

    l = 1190 g / 0.146772 g/cm

    l = 8107.81 cm or 81.7081 m
