Answer:
<em>The volume of water is 3.5 cubic meter</em>
Explanation:
<u>Density </u>
The density of a substance or material is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:
We are given the density of water as .It's required to find the volume of m=3,500 kg of water. Solving for V:
The volume of water is 3.5 cubic meter
