Correct Answer  Option 4 : 8.83 g/cm
3
The correct answer is option 4) i.e. 8.83 g/cm3
CONCEPT:

Density is defined as the amount of mass of an object contained in a given unit of volume.
 The density of an object is given by
Density, \(\rho = \frac{m}{V}\)
Where m is the mass of the object and V is the volume.
EXPLANATION:
Given that:
Mass, m = 106 g
Initial volume, V_{i} = 24 mL
Final volume, V_{f} = 36 mL
Volume of the copper strip,
⇒ V = Vf  Vi = 36  24 = 12 mL = 12 cm^{3}
\(⇒ \rho = \frac{m}{V} =\frac{106}{12} = 8.83\: g/cm^3\)
