On a rectangular piece of cardboard with perimeter $16$ inches, three parallel and equally'spaced creases are made. $($See Figure $1.)$ The cardboard is then folded along the creases to make a rectangular box with open ends. $($See Figure $2.)$ Letting $x$ represent the distance $($in inches$)$ between the creases, use the ALEKS graphing calculator to find the value of $x$ that maximizes the volume enclosed by this box. Then give the maximum volume. Round your responses to two decimal places.

Value of $x$ that maximizes volume: $$ in

Maximum volume: $$ in ${?}^3$
