為什麼幾何包會弄亂我的邊距？

為什麼幾何包會弄亂我的邊距？

我想盡可能多地利用頁面來編寫文件。我正在使用的程式碼是這樣的（免責聲明：我從這裡）：

\documentclass[12pt, oneside, a4paper]{memoir}

\usepackage{layout}
\usepackage{showframe}

%\usepackage[a4paper]{geometry}

\usepackage{amssymb, amsfonts, amsthm}
\newtheorem{problem}{Problem}

\begin{document}
\title{Sample Document}
\author{John Doe}
\maketitle

\layout{}

Here is some sample text to show you what LaTeX does. 

To start a new paragraph, you need to leave a line of white space in your tex file.

To include math, you have two options. The first is called ``in line,'' and you do this by putting your math between two dollar signs (\$). For example, Fermat's Little Theorem tells us that if $p$ is a prime and $a$ is an integer such that $p \nmid a$, then $a^{p-1} \equiv 1 \pmod{p}$. Note that the exponent on $a$ has to go in braces (in the tex file). 

But if you really want an equation (or congruence) to stand out, then you ``display'' the math. It looks like this:
\[
    a^{p-1} \equiv 1 \pmod{p}.
\]
Nice, right?

Finally, we can make things look really nice for homeworks as follows:

\begin{problem}
    Let $X$ and $Y$ be blah blah blah \ldots
\end{problem}

\begin{problem}
    Let $X$ and $Y$ be as in the previous problem. What is $Z$?
\end{problem}

Notice that LaTeX automatically numbers the problems for us. 

\end{document}

看起來不錯，但側面有很多未使用的紙張： 無幾何形狀

然而，一旦我取消註釋調用幾何包的行，邊距就會變得混亂，即使我什至沒有發出任何命令來改變它們。 幾何學

我嘗試查看一些資料來源，但他們沒有提到發生這樣的事情，所以我想了解為什麼幾何會出現這種情況。

另外，如果可能的話，一些幫助使代碼正確，以盡可能少地留下未使用的紙張空間。

memoir有自己的定義頁面佈局的方法，最好不要使用geometry它。下面的 MWE 透過減少邊距來增加文字區塊的大小。

% memgeomprob.tex  SE 562072

\documentclass[12pt, oneside, a4paper]{memoir}

\setlrmarginsandblock{0.8in}{*}{1.0} % set left/right margins to 0.8in
\setulmarginsandblock{1in}{*}{1.0}   % set upper/lower margins to 1in
