A box is to be constructed from a sheet of cardboard that is 20 cm by 60 cm, by cutting out squares of length x by x from each corner and bending up the sides. What is the maximum volume this box could have?
I think to calculate the volume of this box is that you should consider that the both side of the cube or box is equals to each other which means that the 20 by 60 card board would become 20^3 and the answer is 8000 cm3. I hope this would help you and feel free to ask for more
