V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=\stackrel{cm}{4}\\
h=\stackrel{cm}{12}
\end{cases}\implies V=\pi (4)^2(12)\implies V=192\pi~cm^3 [/tex]
192π is about 603.19 cm³.
well, it means if you grab a hmmmm cube, say that is 1cm x 1cm x 1cm, namely a 1cm tall, 1cm wide and 1cm long, whose value is 1cm³, you can fit 603.19 of those in that cylinder.
