A \(\displaystyle 6\)-kg plastic tank that has a volume of \(\displaystyle 0.18 \ \text{m}^3\) is filled with liquid water. Assuming the density of water is \(\displaystyle 1000 \ \text{kg/}\text{m}^3\), determine the weight of the combined system.

Remember that the unit of weight in SI units is - newton.

\(\displaystyle m = m_1 + m_2 = m_1 + \rho V = 6 + 1000(0.18) = 186 \ \text{kg}\)

Then, the weight is:

\(\displaystyle W = mg = 186(9.8) = \textcolor{blue}{1822.8 \ \text{N}}\)
