I am trying to determine the cost and amount of material needed for this project. i am using plywood to make a box
that fits some equipment. the box size i need is 5ft x 4 ft. I need to use the minima function but i don't know where to start. I know that V=LWH but I am not sure where to start with that either. Any help would be great. Also guess i could use a price point from looking at how much a sheet of plywood costs of around $13.85 per sheet at 4ftx8ft. I need to figure out minimum cost of material and surface area required.
