The number of wheels and windows in the world is difficult to determine precisely, as they exist in various forms and are constantly being produced and used. However, it is reasonable to assume that there are far more windows in the world than wheels.
Windows are a common architectural feature found in buildings, vehicles, and numerous other structures worldwide. Considering the vast number of buildings, houses, cars, trains, planes, and other objects that incorporate windows, it is likely that the total number of windows far exceeds the number of wheels.
On the other hand, while wheels are also quite ubiquitous, they are primarily found in transportation vehicles like cars, bicycles, trucks, and industrial machinery. While these vehicles are numerous, they may not outnumber the vast number of buildings and structures that have windows.
Ultimately, without precise data, it is challenging to determine the exact number of wheels or windows in the world. However, given the prevalence of windows in buildings and various objects, it is likely that there are more windows than wheels overall.
