To find the density (\( \rho \)) of the object, you would use the formula:
\[ \rho = \frac{m}{V} \]
where \( m \) is the mass of the object, and \( V \) is the volume it displaces.
Given that the mass \( m \) of the object is 5.6 kg and it displaces 1 liter (L) of seawater, we need to convert the volume into cubic meters (m³) since density is typically expressed in kilograms per cubic meter (kg/m³).
1 liter is equivalent to 0.001 cubic meters (1 L = 0.001 m³).
Now, you can calculate the density of the object:
\[ \rho = \frac{m}{V} = \frac{5.6 \ \text{kg}}{0.001 \ \text{m}^3} \]
\[ \rho = \frac{5.6 \ \text{kg}}{0.001 \ \text{m}^3} \]
\[ \rho = 5600 \ \text{kg/m}^3 \]
Thus, the density of the object is 5600 kg/m³.
