###### Example6.5.8

A rectangular prism's volume can be calculated by the formula

\begin{equation*}
V=Bh
\end{equation*}

where \(V\)stands for volume, \(B\) stands for base area, and \(h\) stands for height. A certain rectangular prism's volume can be modeled by \(4x^3-6x^2+8x\) cubic units. If its height is \(2x\) units, find the prism's base area.
