Appreciation of an outdoor swimming pool with a volume of 140 cm3

Quick answer：

This term seems to be a misunderstanding, as 'cm3' is a unit of volume and cannot be associated with a swimming pool. It is likely that there is an error in the term. A standard outdoor swimming pool would typically be measured in cubic meters (m3). If you are referring to a small pool or pond with a volume of 140 liters (0.14 m3), it would be an unusually small swimming pool. Appreciating such a pool might involve considering its design, the materials used, and its purpose in the context of the surrounding environment.
