A 16cm x 30cm sheet of rectangular cardboard is folded such that an open top box is created. What is the volume equation that models all of the boxes that can be from the piece of cardboard? Choose all that apply.

v(x)=(30−2x)(16−2x)xv\left(x\right)=\left(30-2x\right)\left(16-2x\right)x

v(x)=4x2−92x+480v\left(x\right)=4x^2-92x+480

v(x)=4x3−92x2+480xv\left(x\right)=4x^3-92x^2+480x

v(x)=4x3+92x2−480xv\left(x\right)=4x^3+92x^2-480x
