Are there more Doors or Wheels in the world

Achem.

This should help clear up the debate once and for all. PLEASE NOTE- I AM MAJORLY APPROXIMATING AND USING UNRELIABLE DATA. I AM ALSO NOT INCLUDING A LOT OF FACTORS, ONLY ONES THAT SEEM MAJOR We are going to calculate this in the amount made since 2000 -- Let's start with wheels. Lego wheels, to be exact. 318 Million lego wheels are made every year. That means, Since 2000, lego has made 6,996,000,000 wheels (nice) Now, onto cars. 78 million cars are made a year, that's 1,716,000,000 cars since 2000. Each car has 4 wheels, so that's 6,864,000,000 wheels since 2000 Add those together, and that's 13,860,000,000 Wheels since 2000 -- Now, onto doors. 1300 buildings are built each day. Assuming each building has 2 doors, thats 208,780,000 doors since 2000 but then factor in cars I'm just going to use 3 doors, because it's between 2 and 4 Using the 78 million cars made a year stat (1,716,000,000 cars since 2000), we can figure out that there have been 5,148,000,000 doors on cars since 2000. 5,356,780,000 doors combined, since 2000 -- This means that wheels wins by 8,503,220,000 -- However, I'm leaving out a major factor: Office Buildings. This is where the data gets extremely unreliable, feel free to go off the previous data. -- There are 5.9 million commercial buildings in the US alone. The US is 3.797 million mi² in area. This means there are 1.55 office buildings per square mile. The land area of the world is 57,308,738 miles squared (only land, not sea) 1.55 * 57,308,738 =

88,828,543.9 office buildings in the world (again, innacurate, but it's math) Using only data from new york (which I know is bad) The average height of each building is 18.7 floors I'm going to pick an arbitrary number of 20 rooms per floor Now, we have our preliminary data and we can start to figure out how many doors + wheels are in these office buildings. -- For wheels There are 1,661,093,770.93 floors in the world. At 20 rooms per floor, that's 33,221,875,418.6 rooms. Each room has 1 office chair. Each office chair has 6 wheels. 33,221,875,418.6 * 6 = 199,331,252,511.6 wheels. In total, there are 199,331,252,511.6 wheels in office buildings around the world. -- For doors, it's the amount of rooms. There are 33,221,875,418.6 doors in office buildings around the world. -- Add those to our previous numbers (with rounding), and we have For Wheels: 213,191,252,512 Wheels since 2000 For Doors: 38,578,655,419 doors since 2000 Wheels wins by 174,612,597,093. ---- IN CONCLUSION In both scenarios, wheels wins. The second addition of office buildings is much more unreliable than the original one. However, both are unreliable. Also, a lot of sources of wheels and doors were not added. (suitcases, 18wheelers, factories, etc) --

wheels for sure
