    Find the dimensions of the largest office that can be redecorated for a fixed cost C.

    In redecorating an office, the cost of new carpeting is five times the cost of wallpapering a wall. Find the dimensions of the largest office that can be redecorated for a fixed cost C. (Hint: Maximize V = xyz subject to 5xy + 2xz + 2yz = C)
