Box Problem • Advanced Algebra Students, Inc. is designing cardboard boxes without a top. The boxes will be made from a single sheet of cardboard where the corners will be cut out, then folded up to make a box.
Box Problem • The company wants to maximize the volume of the box. To do so, you decide to write a function that would describe the total volume of the box given the length “x” of one side of the cutout.
Box Problem • The company wants to maximize the volume of the box. To do so, you decide to write a function that would describe the total volume of the box given the length “x” of one side of the cutout.
Box Problem • You are given the original sheet of cardboard is 12 inches X 20 inches
Box Problem • You are given the original sheet of cardboard is 12 inches X 20 inches
Box Problem • With your partner write a function to describe the volume “V(x)” based on the length of the cutout “x”
Box Problem • V = L*W*H • H = x • L = 20 – 2x • W = 12 – 2x • V(x) = (20-2x)(12-2x)x
Box Problem • Use your calculator to determine the maximum volume of the function • Coordinates of Relative Maximum:(2.43, 262.68) • Thus the maximum volume is 262.68 in3
Box Problem • What would be the dimensions of the box that would produce that maximum volume? • H = 2.43 • L = 20-2(2.43) = 15.15 • W = 12-2(2.43) = 7.15 • 15.15in x 7.15in x 2.43in
