An aquarium

An aquarium tank that measures 2.4 m high, 6 m long, and 1.5 m wide and is completely filled with water. The density of water is 1,000 kg/m³. What is the mass of the water in the tank?

Correct answer:

m =  21600 kg

Step-by-step explanation:

$$\begin{gathered} a=6\text{ m } \\ b=1.5\text{ m } \\ c=2.4\text{ m } \\ V=a\cdot b\cdot c=6\cdot 1.5\cdot 2.4={\displaystyle \frac{108}{5}}=21.6{\text{m}}^3 \\ \rho =1000{\text{kg/m}}^3 \\ m=\rho \cdot V=1000\cdot 21.6=21600\text{ kg} \end{gathered}$$
