A box of volume 216 m with a square bottom and no top is made of two different materials. The cost of the bottom is $40/m and the cost of the sides is $30/m. Find the dimensions of the box that minimize the total cost. (Use symbolic notation and fractions where needed. Write the objective function with respect to the length of the square bottom.) length of the bottom side: 6.868 Incorrect height of the box: 4.579 Incorrect m m Brandon is on one side of a river that is 70 m wide and wants to reach a point 200 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 m/s and run at 4 m/s. (Use decimal notation. Give your answer to two decimal places.)
