Answer 3

remember, \[density =\frac{ mass }{ volume }\]

so, how would you calculate the density of objects A and B?

Would you like to do the math?

Answer 4

12/8?

Answer 5

Object A:

\[density =\frac{ 12 }{ 8 }=~?\]

Object B:

\[density =\frac{ 20 }{ 8 }=~?\]

Once you figure that out, you subtract to find your final answer:

Object `B` - Object `A` = ?
