Density of 6.8cm 14.5cm 8.6cm

**

1. Identify the given dimensions:
\text{length} = 6.8 \, \text{cm}
\text{width} = 14.5 \, \text{cm}
\text{height} = 8.6 \, \text{cm}

2. Calculate the volume \( V \):
V = 6.8 \times 14.5 \times 8.6

3. Use the volume in the density formula:
\rho = \frac{m}{6.8 \times 14.5 \times 8.6}

4. Since mass \( m \) is unknown, this is the resulting formula for density.

Final answer in step-by-step is:
\rho = \frac{m}{6.8 \times 14.5 \times 8.6}
