140cm3 open-air swimming pool design drawing

Quick answer：

The user is asking for a design drawing of an open-air swimming pool with a volume of 140cm3. This is an unusual request as typically swimming pools are much larger than 140cm3. A design drawing would typically include dimensions, architectural features, materials, and structural details. If the user is referring to a conceptual or miniature model for an art project or educational purposes, the drawing would focus on scale, aesthetics, and functionality within the confines of the small size.
