# Creating box on long enumeration

Hello so I want to make a box outside of enumeration:

\noindent\fbox{
\parbox{\textwidth}{
\begin{enumerate}
\item Matriks contoh merupakan matriks berukuran 2x2 seperti berikut: \\
$\begin{pmatrix} 5 & 0\\ 0 & 0 \end{pmatrix}$
\item Kemudian mencari matriks S dengan menggunakan rumus 2.2 hingga 2.3.\\
$AA^T$=
$\begin{pmatrix} 5 & 0\\ 0 & 0 \end{pmatrix}$
*
$\begin{pmatrix} 0 & 0\\ 0 & 5 \end{pmatrix}$
=
$\begin{pmatrix} 4 & 0\\ 0 & 4 \end{pmatrix}$ \\\\
$det(AA^T-\lambda \textit{I}) = 0$\\\\
det
$\begin{pmatrix} 4 & 0\\ 0 & 4 \end{pmatrix}$
- $\lambda$
$\begin{pmatrix} 1 & 0\\ 0 & 1 \end{pmatrix}$
= 0 \\

det
$\begin{pmatrix} 4 & 0\\ 0 & 4 \end{pmatrix}$
-
$\begin{pmatrix} \lambda & 0\\ 0 & \lambda \end{pmatrix}$
= 0 \\

det
$\begin{pmatrix} 4-\lambda & 0\\ 0 & 4-\lambda \end{pmatrix}$
= 0 \\

...

\begin{pmatrix}
1 & 0\\
0 & 1
\end{pmatrix}
$\end{enumerate} }}  But then I add the fbox and parbox like in this solution but it seems that the content kinda hidden at the end of the first page of the box. Any help? • Please add a compilable MWE. – Raaja Feb 7 at 14:24 ## 1 Answer Existing suggestion works fine, please refer: \documentclass{book} \usepackage{framed,amsmath} \begin{document} \begin{framed} \begin{enumerate} \item Matriks contoh merupakan matriks berukuran 2x2 seperti berikut: \\$\begin{pmatrix}
5 & 0\\

\end{pmatrix}$\item Kemudian mencari matriks S dengan menggunakan rumus 2.2 hingga 2.3.\\$AA^T$=$\begin{pmatrix}
5 & 0\\
0 & 0
\end{pmatrix}$*$\begin{pmatrix}
0 & 0\\
0 & 5
\end{pmatrix}$=$\begin{pmatrix}
4 & 0\\
0 & 4
\end{pmatrix}$\\\\$det(AA^T-\lambda \textit{I}) = 0$\\\\ det$\begin{pmatrix}
4 & 0\\
0 & 4
\end{pmatrix}\$
\end{enumerate}
\end{framed}

\end{document}

• Thank you, I thought I cannot use the frame because there is error. it seems my document adds the "use package" in separates documment so i dont know i must include it. – Bob Nathan ZeonBe Feb 8 at 8:55
