Maximizing the Volume of an Open Top Box by Graphing
An open-top box is to be constructed from a 6 foot by 8 foot rectangular cardboard by cutting out equal squares at each corner and the folding up the flaps. Let x denote the length of each side of the square to be cut out.
a) Find the function V that represents the volume of the box in terms of x.
b) Graph this function and show the graph over the valid range of the variable x..
Using the graph, what is the value of x that will produce the maximum volume?
2. The volume of a cylinder (think about the volume of a can) is given by V = pi r^2 h where r is the radius of the cylinder and h is the height of the cylinder. Suppose the volume of the can is 100 cubic centimeters.
a) Write h as a function of r. Keep "pi" in the function's equation
