    19738.83 g

    Explanation:

    Volume = L · H · W

    Convert 1.24 ft to cm = 37.79 cm

    Convert 4.95 in to 12.57 cm

    5.28 cm * 37.79 cm * 12.57 cm = 2508.11 cm^3

    Density = 7.87 g/cm^3

    Density = mass / volume

    Mass = density * volume

    Mass = 7.87 g/cm^3 * 2508.11 cm^3 = 19738.83 g
