5. The six faces of a unit cube are painted in 6 different colors, and a different number of roosters are drawn on each face. The colors and the number of roosters on each face correspond as shown in Table 1:
Table 1
\begin{tabular}{|c|c|c|c|c|c|c|}
\hline Color on the face & Red & Yellow & Blue & Green & Purple & Green \\
\hline Number of roosters on the face & 1 & 2 & 3 & 4 & 5 & 6 \\
\hline
\end{tabular}

Take 4 of the above unit cubes and arrange them to form a horizontally placed rectangular prism as shown in Figure 1. Then, the total number of roosters on the bottom face of this rectangular prism is $\qquad$.

Note: There is a minor error in the table where "Green" is listed twice. It should be "Green" and "Cyan" to match the original Chinese text. Here is the corrected version:

Table 1
\begin{tabular}{|c|c|c|c|c|c|c|}
\hline Color on the face & Red & Yellow & Blue & Cyan & Purple & Green \\
\hline Number of roosters on the face & 1 & 2 & 3 & 4 & 5 & 6 \\
\hline
\end{tabular}
5.17.

Since the 4 aforementioned unit cubes are identical, it can be observed that the colors of the 4 adjacent faces to the red face are blue, yellow, cyan, and purple, so the color of the face opposite the red face is green. The colors of the 4 adjacent faces to the yellow face are cyan, blue, red, and green, thus the color of the face opposite the yellow face is purple. The only remaining possibility is that the face opposite the cyan face is blue, which is the color of the top face of the rectangular prism. The corresponding bottom face color and the number of golden roosters on that face are:
$$
\begin{array}{l}
\text { Top }(\text { Yellow }) \longleftrightarrow \text { Bottom }(\text { Purple }) \longleftrightarrow 5 \text {; } \\
\text { Top }(\text { Purple }) \longleftrightarrow \text { Bottom }(\text { Yellow }) \longleftrightarrow 2 \text {; } \\
\text { Top }(\text { Red }) \longleftrightarrow \text { Bottom }(\text { Green }) \longleftrightarrow 6 \text {; } \\
\text { Top }(\text { Blue }) \longleftrightarrow \text { Bottom }(\text { Cyan }) \longleftrightarrow 4 \text { . }
\end{array}
$$

Therefore, the bottom face of this rectangular prism has a total of 17 golden roosters.
