A graphing calculator is recommended. In this problem you are asked to find a function that models a real-life situation and then use the model to answer questions about the situation. Use the guidelines on page 237 to help you. A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions 14 in. by 20 in. by cutting out equal squares of side x at each corner and then folding up the sides (see the figure) 20 in. х х х 14 in х X X (a) Find a function that models the volume V of the box 280x 32x24x3 X V(x) (b) Find the values of x for which the volume is greater than 230 in3. (Round your answers to three decimal places. Enter your answer using interval notation.) (c) Find the largest volume that such a box can have. (Round your answer to three decimal places.) in3
