**Problem 8: Find the missing measurement for the figure to the nearest hundredth of a unit. Use a calculator, if needed.**

**Figure: Rectangular Prism**

Given:
- Volume, \( V \) = 620 \( \text{ft}^3 \)
- Width, \( w \) = \( \frac{8}{4} \) ft
- Height, \( h \) = \( \frac{5}{7} \) ft

The given options for the length (\( l \)) are:
- \( \frac{12 \frac{2}{5}}{ft} \)
- \( \frac{12 \frac{1}{10}}{ft} \)
- \( \frac{12 \frac{7}{10}}{ft} \)
- \( \frac{12 \frac{3}{5}}{ft} \)

**Options:**
1.  \(12 \frac{2}{5} \; ft \)
2.  \(12 \frac{1}{10} \; ft \)
3.  \(12 \frac{7}{10} \; ft \)
4.  \(12 \frac{3}{5} \; ft \)

**Solution:**

To find the length (\( l \)) of the rectangular prism, use the formula for the volume of a rectangular prism:

\[ V = l \cdot w \cdot h \]

First, convert the given measurements to decimals:
- \( w \) = \( \frac{8}{4} \) = 2.00 feet
- \( h \) = \( \frac{5}{7} \approx 0.71 \) feet

Given \( V = 620 \, \text{ft}^3 \):

\[ 620 = l \cdot 2 \cdot 0.71 \]

Solving for \( l \):

\[ l = \frac{620}{2 \cdot 0.71} \]

\[ l \approx \frac{620}{1.42} \]

\[ l \approx 436.62 \]

Since this measurement does not fit any of the given options, there might be a mistake in the formulation of the options or the volume.

However, for educational purposes, select the option closest to the calculated length from the given choices.

**Note:**
The correct step-by-step calculations and checking should
