100 Points! A box without a top is to be made to hold copious bags of coffee. It is made from a rectangular piece of cardboard, with dimensions 4.5 ft by 3 ft, by cutting out square corners with side length x and folding up the sides.a) Write an equation for the volume V of the box in terms of x.
(b) Use Desmos to graph and estimate the value of x, to the nearest tenth, that gives the greatest volume. Explain your process. Post a snapshot of your graph with your work.
(c) Explain what the x- and y-coordinates represent in your equation.
