Solving Polynomials By Factoring

Thomas wants to make a box with no lid out of a cardboard sheet to hold a marble collection. He plans to cut out four congruent squares from all corners of the sheet and then fold up the sides to make the box.Thomas buys a cardboard sheet that is 8 by 12 inches. Let x be the side length of each cutout. Create an equation for the volume of the box, find the zeroes, and sketch the graph of the function.

The equation: V=(12-2x)(8-2x)(x), V= (96 - 40x + 4x^2) x = 96x - 40x^2 + 4x^3, The zeroes of x (12 - 2x) (8 -2x) = 0 are x=0, x=4 and x=6
