Mathematica code to Latex

I want to export my Mathematica code to Latex, so I saved the mathematica notebook as LaTeX document. Copying this latex code to overleaf, I get the attention message "\hbox too wide" and the text crosses the page borders. How could I fix this?

My code is the following:

\documentclass{article}
\usepackage{amsmath, amssymb, graphics, setspace}

\newcommand{\mathsym}[1]{{}}
\newcommand{\unicode}[1]{{}}

\newcounter{mathematicapage}
\begin{document}

\begin{doublespace}
\noindent\(\pmb{w[2]\text{:=}3*(\text{Pi}{}^{\wedge}2)/2;}\)
\end{doublespace}

\begin{doublespace}
\noindent\(\pmb{w[3]\text{:=}4*(\text{Pi}{}^{\wedge}2);}\)
\end{doublespace}

\begin{doublespace}
\noindent\(\pmb{\text{k222}[\text{x$\_$},\text{t$\_$}]\text{:=}- 
\text{Sqrt}[2/3]*\text{Pi}{}^{\wedge}2*(\text{Sin} 
[\text{Pi}*x]+4*\text{Sin}[2*x*\text{Pi}]*\text{Exp} 
[I*w[2]*t]+9*\text{Sin}[3*x*\text{Pi}]*\text{Exp}[I*w[3]*t])}\)
\end{doublespace}

\end{document}
