How to increase the height of a box which contains equation ?

[Taechul Lee]

Thank you all the folks at comp.text.tex
I solve a problem with your helps

BUT I still have a question about a box.
When I want to increase the width of a box, I can do that just add a hspace
command to the both ends.

\begin{equation}
\fbox{
\hspace{.1cm}
$\displaystyle A \equiv B $
\hspace{.1cm}
}
\end{equation}

However, I don't know how to increase the height of a box.
vspace command does not work.
How can I increase the height of a box ?

Thank you very much in advance

Regards,

you should perhaps consider the \boxed command from the amsmath package

\[ \boxed{a=b} \]

otherwise just use \vphantom{something that have some height}

perhaps use a \rule or something else

use the \strut command or \rule[lift]{width}{height}

something like \rule[-1ex]{0pt}{2ex}

perhaps, as long as the width is 0pt you will not be able to the the line

surely you don't want to do such tedious stuff? make the separation
the same all the way round:

\begin{equation}
\setlength{\fboxsep}{.1cm}
\fbox{%
$\displaystyle A \equiv B $%
}
\end{equation}
