An open box of maximum volume is to be made from a square piece of material, s = 12 centimeters on a side, by cutting equal squares from the corners and turning the sides (see figure). (a) Analytically complete six rows of a table such as the one below. (The first two rows are shown.) Length and Height, x Volume, V Width 1 12 - 2(1) 1[12 - 2(1)]2 = 100 2. 12 - 2(2) 2[12 - 2(2)]? = 128 31 12 2(3) 3[12 - 2(3)]2 = 12 - 2(4) 4[12 - 2(4))? = 4 5. 12 - 2(5) 5[12 - 2(5)]? = 12 - 2(6) 6[12 - 2(6)]? = Use the table to guess the maximum volume. V = (b) Write the volume Vas a function of x. V = OSx< 6 (c) Use calculus to find the critical number of the function in part (b) and find the maximum value. V= from the oanh
