    Answer: The mass of solid a is 4800 grams

    Step-by-step explanation:

    Hi, to answer this question we have to apply proportions:

    For solid b = 40.32 cm2 / 6912 grams

    For solid a = 28 cm2 / x grams

    Where x is the mass of solid a.

    So:

    40.32 / 6912 = 28 / x

    x = 28 / (40.32 / 6912)

    x = 4800 grams

    The mass of a is 4800 grams

    Feel free to ask for more if needed or if you did not understand something.
