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.
