The volume of the pan is given by:
[tex]V=lwh[/tex]since it is shaped as a rectangular prism.
In this case we know the volume, the length and the width; plugging this values we can find the height:
[tex]\begin{gathered} 252=(12)(1012)h \\ h=\frac{252}{(12)(1012)} \\ h=0.021 \end{gathered}[/tex]Therefore, the height of the pan is 0.021 inches.
