    Explanation:

    5 kg = 5 kg * 1000 grams / kg = 5000 grams

    10 cm does not require any conversion.

    50 mm = 50 mm * 1 cm/10 mm = 5 cm

    0.2 m = 0.2 m * 100 cm / 1 m = 20 cm

    V = 10 cm * 5 cm * 20 cm

    V = 1000 cm^3

    Density = 5000 grams / 1000 cm^3 = 5 grams / cm^3

    B
