Answer:
Density = 0.2 g/cm³
Step-by-step explanation:
The density of a substance can be found by using the formula
![Density = (mass)/(volume)](https://img.qammunity.org/2021/formulas/chemistry/high-school/el4r75hf1brsg5k4a45db8ptpkl6z9kys6.png)
From the question
mass of cube = 15 g
volume = 75 cm³
Substitute the values into the above formula and solve for the density
That's
![Density = (15)/(75)](https://img.qammunity.org/2021/formulas/chemistry/high-school/zgczds7l1475bceqg8fe60m96jpyuul76w.png)
Density = 0.2 g/cm³
Hope this helps you
