Answer:
The answer is
1.61 g/cm³
Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} [/tex]
From the question
mass = 12.9 g
volume = 8 cm³
The density of the block is
[tex]density = \frac{12.9}{8} \\ = 1.6125[/tex]
We have the final answer as
1.61 g/cm³
