Answer :
In order to calculate the carton's height, let's first convert from liters to cm³.
1 liter is equal to 1000 cm³.
Now, let's use the volume formula of a rectangular prism to calculate the height:
[tex]\begin{gathered} V=A\cdot h \\ 1000=50\cdot h \\ h=\frac{1000}{50} \\ h=20\text{ cm} \end{gathered}[/tex]So the height is 20 cm.
