Throughout the ages and in different countries, number systems were     developed and used to help people
count and communicate with numbers. From the ancient Egyptians to     the modern day, different systems have
used pictures and symbols to represent whole numbers. Some of the     well-known number systems are the
Egyptian, Babylonian, Roman, modern Chinese and the Hindu-Arabic or     decimal system.

以下是与以下内容相关的答案图形标题在浮动内，带有浮动。我给出了您原始环境的替代方案textbyfigure，但您也可以保留您的版本：

\documentclass{article}
\usepackage{lipsum}
\usepackage[many]{tcolorbox}
\usepackage{caption}

\newcommand{\mygraphics}[3][]{%
  \tcbincludegraphics[nobeforeafter,
    blanker,hbox,
    minipage boxed title*=-6mm,
    title={\captionsetup{skip=0pt}\captionof{figure}{#3}},
    attach boxed title to bottom center,
    boxed title style={enhanced,size=title,sharp corners,
      boxrule=0pt,frame hidden,colback=green!50!black!25},
    #1]{#2}%
}

\newsavebox\mysavebox

\newenvironment{textbyfigure}[1]{%
  \sbox{\mysavebox}{#1}%
  \begin{tcolorbox}[blanker,
    beforeafter skip=8pt,
    sidebyside,sidebyside gap=5mm,
    sidebyside align=top,
    righthand width=\wd\mysavebox,]%
}{%
  \tcblower%
  \raisebox{\the\dimexpr-\ht\mysavebox-\dp\mysavebox+\baselineskip/2\relax}{\usebox{\mysavebox}}%
  \end{tcolorbox}
}
