Density of water 1000kgper m^3 What will be the volume of 3500<br>kg water​
skad [1K]

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:

\displaystyle \rho=\frac{m}{V}

We are given the density of water as \rho=1,000\ kg/m^3.It's required to find the volume of m=3,500 kg of water. Solving for V:

\displaystyle V=\frac{m}{\rho}

\displaystyle V=\frac{3,500}{1,000}

V=3.5\ m^3

The volume of water is 3.5 cubic meter
