# How to make an empty box

I am making a sheet where people can fill in answers of various types. For this I would like to make some boxes of certain width and height. How can this best be done? I use \fbox when I want to box a box around some text, but now I need to make a box with given dimensions.

I did noticed the question What are the different kinds of boxes in (La)TeX? but don't quite see the answer there.

You can use \framebox(200,300){} where the size is given in multiples of \unitlength, defaulting to 1pt.

Surprised no one has mentioned this. Latex has feature specifically for questions and answers:

% allow for answer boxes:
\documentclass[12pt]{exam}

\usepackage{amsmath}

\begin{document}
\begin{enumerate}

% questions can be list items
\item (Problem 7 \S 2.1)\\
Evaluate the following expression using Euclid's algorithm (2.1.3). (\textbf{Write each step down for credit})

$\gcd(98,\ 35)$

$98\mod 35 = 28$ \\
$35\mod 28 = 7$ \\
$28\mod 7 = 0$ \\
$\gcd(98,\ 35) = 7$
