The formula to calculate the weight per volume (WPV) is:
\[ WPV = \frac{m \cdot 9.81}{V} \]
Where:
Let's say the total mass (m) is 50 kg and the total volume (V) is 2 m³. Using the formula:
\[ WPV = \frac{50 \cdot 9.81}{2} \]
We get:
\[ WPV = 245.25 \, \text{N/m}^3 \]
So, the weight per volume is approximately 245.25 N/m³.
