Recall the formula for density, which is defined as mass divided by volume: \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
Identify the given values from the problem: mass \(m = 30\ \text{kg}\) and volume \(V = 15\ \text{m}^3\).
Substitute the known values into the density formula: \(\text{density} = \frac{30\ \text{kg}}{15\ \text{m}^3}\).
Perform the division to find the density value (do not calculate the final number here, just set up the expression).
Express the units clearly as kilograms per cubic meter (\(\text{kg/m}^3\)) to complete the answer.
