I rotated and darkened your sketches.
Looks like a 13" diameter, 18" tall lidded trash can with rubber seals for lid and top of the can and a basketball backboard on the inside of the lid plus other interactive toys on the outside of the container.
Of course this sounds like it is a school project to teach you how to design things and over come production problems.
Are you allowed to use something other than wood or is that what the assignment requires? I know we had projects like this that called for specific materials to be used and also listed hardware and adhesive types that could and could not be used.
If you are required to use wood then:
1. The bending ply mentioned would be a good choice. Knowing the required dimensions lends itself to cut the plywood at the correct angles and the right length to form a good tight joint . Would it be cost effective? Cost of the plywood will be high but could save time in your manufacturing process. That's for you to determine.
2. Stave construction is another consideration. To be cost effective you would have to research the wood available to the manufacturing plant. Are there local woods available that are ready for use? Can you buy wood and have it shipped cheaper than local sources? Will you require the wood to be processed or do you have to allow for the cost of the extra machinery needed to process the lumber? This being a straight sided vessel so all the parts can be made identical and jigs could be easily made to facilitate the manufacturing process. Will you buy the parts of make them yourself. Again would it be cost effective?
3. Veneer on a substrate would also be a consideration. Being a cylinder it would be easy to apply veneer to if the substrate material is flat and you would have the look of wood.
