[Tex/LaTex] Show integration limits above & below the integral

Question

Well considering this code, the "E" is shown after the integral:

\begin{equation}
m = \iiint_E \rho \ \mathrm{d}V
\end{equation}

The limit is shown slightly behind the number, how can I place it in the middle below the triple integral?

Answer 1

You need to insert \limits after \iiiint:

\documentclass{article}
\usepackage{amsmath} % for \iiint macro
\begin{document}
\begin{equation}
m = \iiint\limits_E \rho \, \mathrm{d}V
\end{equation}
\end{document}
