Currently doing a problem with max/min problems and Maximizing the volume.
A sheet of cardboard 30cm by 40cm is to be cut into a box with a lid. The box shape is one of a rectangular cereal box.
I have worked the total area to be:
120cm^2 = 2zy + 2xy + 2xz
But im now stuck on what to do?
I need to find the dimensions that will maximise the volume and prove that its a maximum.
