a steel bar has a density of 8,000 kilograms per cubic meter and a mass of 400 kilograms. calculate its…

Explanation:

Step1: Recall density formula

The formula for density $\rho$ is $\rho=\frac{m}{V}$, where $m$ is mass and $V$ is volume. We need to solve for $V$, so we can re - arrange the formula to $V = \frac{m}{\rho}$.

Step2: Substitute given values

We are given that $m = 400$ kg and $\rho=8000$ kg/m³. Substituting these values into the formula $V=\frac{m}{\rho}$, we get $V=\frac{400}{8000}$.

Step3: Calculate the volume

$V=\frac{400}{8000}=0.05$ m³.

Answer:

$0.05$ m³
