You are given the job of designing planter boxes constructed completely from plywood. The box needs to have a bottom, four side walls, one dividing wall in the middle (made of plywood as well) and no top. An example is shown below. If the total volume must be 6 cubic meters (i.e. V = xyz = 6 is the given constraint!), then find the minimum cost to produce the box. ( For full credit, in your handwritten work you must correctly find a two-variable function for cost and find its one critical point, then stop. You do NOT have to do the 2nd derivative test). minimum cost in dollars = Don't forget to hit the SUBMIT button below before leaving this question. Show My Work (Required) ?
