Function is in the attachment below.
V = (l)(w)(h) V = (x)(x)(20-x) V = x²(20-x) V = -x³ + 20x²
The volume of the rectangular box with a square base can be modeled by the polynomial function V = − x 2 ( x − 20 ) . Here, x represents the length of a side of the base, and the height is determined by the combined total of x and height being 20 inches. This polynomial is expressed in factored form.
