Airida [17]

Answer:

Density can be defined as the mass per unit volume of a substance:

                      Density = \frac{mass in g}{volume in cm^{3} }

The unknown in the problem is Volume:

                    Volume = \frac{mass}{Density}

                     Volume =   \frac{17.8}{8.9} = 2cm³
