Question

Please help me?? With understandable explanation

Answer 1

$\bf \textit{volume of a rectangular prism}\\\\ V=Lwh~~ \begin{cases} L=length\\ w=width\\ h=height\\[-0.5em] \hrulefill\\ w=36\\ L=83\\ h=44 \end{cases}\implies V=(83)(36)(44)\implies \stackrel{\textit{old volume}}{\boxed{V=131472}} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf V=Lwh~~ \begin{cases} w=\stackrel{halved}{18}\\ L=\stackrel{doubled}{166}\\ h=\stackrel{tripled}{132} \end{cases}\implies V=(166)(18)(132)\implies \stackrel{\textit{new volume}}{\boxed{V=394416}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \cfrac{\stackrel{\textit{new volume}}{394416}}{\stackrel{\textit{old volume}}{131472}}\implies \stackrel{\textit{simplified}}{\cfrac{3}{1}}~\hfill$
