We wanted to see just how two specialists in fully different fields would prize one such question. Pilot Anna Battison and architect Samantha Josephat both answer a mind teaser Google provided to ask task candidates: How many golf balls fit into a Boeing 747? with their different professional backgrounds, the two professionals approached the concern in very different ways.

*Following is a transcript that the video.*

You are watching: How many golf balls fit in a 747

**Anna Battison:** Well, i hope that"s accurate. I feel like I have to maybe asking somebody.

**Samantha Josaphat:** Um, wish me luck.

**Battison:** So, how plenty of golf balls deserve to you fit in a Boeing 747? I... I have no idea.

**Josaphat:** How many tennis balls? Oh, golf...wow. Wow. My an initial step is to measurement the dimension of a golf ball, which I in reality don"t know.

**Battison:** A golf ball is, i don"t know...

**Josaphat:** I"ve never played golf before.

**Battison:** If you play tennis, a small bit smaller than a tennis ball. Josaphat: I"m gonna predict that a golf ball is 4 inch by 4 inch in diameter.

**Battison:** and also a headrest is probably, i don"t know. Here"s my head. For this reason let"s to speak it"s that huge and perhaps that thick. And also now I"m simply trying to failure the seat to figure out how many golf balls are in it. So, in this headrest, over there are around 15. I"m gonna say that there space three rows of three headrests that deserve to fit in the back portion of it. And then I"m gonna to speak there"s two rows of 3 for the bottom part. Climate that provides us three, six, nine on the top, 6 on the bottom. 15 time 15 golf balls in each headrest. There are 15 headrests in the seat. That gives us 225 golf balls every seat.

**Josaphat:** I"m now attempting to attract a plane. I"m together an architect. It"s like, i gotta obtain it right. Oh, gosh! I"m sorry. The looks horrible. Deserve to I simply line up my wings?

**Battison: **This is very bad. So, you have the cabin, i beg your pardon is like, X1, X2 is, like, whereby the passenger goes v all the seats. Those space what the seat are. And then X3, which is, like, the undercarriage, which can be down here, and, friend know, simply where all the luggage goes.

**Josaphat:** as soon as I very first think about the plane and plan, what is a variable that I deserve to replicate countless times? and also that"s the seat.

**Battison***: *In a 747, primarily have actually two seats here, two seats here, one aisle, an aisle, and three seats in the middle. Therefore that"s seven seats throughout in every row.

**Josaphat:** I will certainly assume a Boeing 747 has about 80 rows.

**Battison:** therefore if there room 366 seats, for this reason 366 seat in a Boeing 747, that method that 366 separated by seven would be around 52 rows.

**Josaphat:** Now, if i were come say a typical chair because that a human being is around 18 inches wide and a Boeing 747 has actually three aisles of seating v potentially 4 seats in the middle, three seats on either end, how numerous seats are in just one row?

**Battison:** I"m gonna add two seats per row because there"s one aisle below where ns can add a seat, hypothetically. For this reason if I"m adding two seats every row, the would offer me 104 extra seats the I can fit in because that that very first layer across the bottom. There"s 470 seats on the bottom layer time 225. That gives me 105,750 golf balls.

**Josaphat:** So us have, six and four is 10. For this reason we have actually 10 time 18. That offers us 180 inches. Then us multiply that by 80 rows. That"s 14,400 inches. That"d give me 1,200 feet. So currently we would have to incorporate circulation.

** Battison:** Now, girlfriend gotta think about, those golf balls are really small. I"ve obtained so numerous gaps in between each seat.

**Josaphat:** So, if i were come relate circulation to an airplane, that would typical the aisles the go indigenous the front and also the earlier of the plane, the an are in in between the seats so that everyone can obtain to your seat comfortably. Battison: I"m gonna seriously ballpark this. So, across, I"ve obtained seven seats. Let"s say there are seven gaps wherein 100 golf balls deserve to fit. That"s 7 gaps in each row. So seven times 52 rows is 364. Therefore 364 times, let"s speak in each gap, 100 golf balls deserve to fit, 36,400.

**Josaphat:** And, like, a typical building, in brand-new York City"s traditional of top quality Housing, friend need about 30% of circulation in a space. For this reason what"s 30% that 1,200 feet? That"s 360 feet. That"s 360...square feet. I just realized it"s not simply feet. 1,200 square feet plus 360 offers us 1,560 square feet. Therefore that includes seats and also circulation.

**Battison:** So, now I"m gonna snapshot how numerous layers of seats can I ridge on top of each various other in that space in the cabin. I"m gonna say possibly three rows, just "cause the seats room high. So then I"m gonna do that number time three, 317,250 golf balls. That"s how plenty of golf balls I have actually in three layers that seats. And that come out as being 353,650.

**Josaphat:** now we have to think around the cockpit, where the pilot is, and also areas for enjoy the meal prep and also the bathrooms.

**Battison: **X2 is very big, right? It"s, like, 52 rows plus the room on top. So I"m gonna speak there"s, friend know, gotta it is in at least 10 that"ll fit in there. Now, possibly that"s a little bit overestimating, but I think ns underestimated because that the lot of golf balls anyway. For this reason let"s just go through that.

**Josaphat:** So, I"m just gonna estimate 40%. "Cause generally in a building, you need to think about, 40% of the room goes to infrastructure, like mechanical systems and also plumbing.

**Battison:** therefore if there room 353,650 golf balls the fit right into the cabin, there would be 10 the fit in there, so that number divided by 10. That"s gonna it is in 35,365.

**Josaphat:** What"s 40% of 1,560 square feet? So currently we"ll carry out 624 plus 1,560, and also that"ll get us 2,184. So now we have actually the floor plan covered. And now we have to think about it in volume.

**Battison***: *The X3 is what we have actually left.

**Josaphat:** common height in an apartment in brand-new York could be around 8 to 10 feet high. And also then the elevation of the carry-on luggage. Therefore we"ll to speak 11 feet head clearance, and then we"ll add an additional two feet because that the material of the plane. And also so that"s 13 feet height.

**Battison:** ns don"t actually know precisely how huge a 747 is, but I would imagine very, very big.

**Josaphat:** Now, if we have to take into consideration the an are below where the baggage claim is, typically, someone have the right to actually to walk in that space to seize luggage.

**Battison:** I would say the it"s about the same size as the cabin or maybe even bigger.

**Josaphat:** and so I will just twin that height and also make that 26 feet. Currently I will multiply 26 feet by 2,184 square feet.

**Battison:** The grand complete is currently 35,365 plus 353,650 add to 353 again, 650, equals 742,665. For this reason that"s our grand total for a 747 the does no actually have actually the 366 seats.

**Josaphat***: *So, my last action would be to divide the total cubic feet that the plane by the cubic feet the I"ve figured out for the golf ball.

**Battison:** but if we have actually an airliner, us do have actually those seats that can"t hold the golf balls.

**Josaphat:** 56,784 cubic feet separated by 12 cubic feet. That complete answer would certainly be 4,732 golf balls*. *

**Battison: **If it has 366 seats, 366 seats times yet many golf balls have the right to fit into each seat, we stated was 225. So 366 time 225 would give us 82,350.

**Josaphat***: *That yes, really does no feel real. I"m not comfortable through that answer.

**Battison:** for this reason I"m going to do this number minus this number to acquire our grand full for an airline 747. Provides us 660,315 golf balls.

**Josaphat:** Oh, I understand what the problem is. I did 12 cubic feet, no 12 cubic inches. For this reason there"s actually one more step. That would certainly be multiply by 12. Oh, that"s funny. Which would give me 56,784 golf balls. Last answer.

**Battison:** I have a gut feeling that that"s method too little.

**Josaphat:** It might be a small bit low still. I mean, I"m gonna need to trust the math at this point.

**Battison:** I assumed I would come the end to a number the was possibly a million or so. Ns think i told you, a headrest is about, like, this big.

**Josaphat:** therefore if i were to go back, I"d most likely tweak the dimension of the golf ball.

**Battison:** i think far more than 15 golf balls deserve to fit into there. Maybe much more along the selection of 25 or 30 golf balls. In aviation, they always want you to refer ago to, girlfriend know, facts. You"re always supposed to follow her checklist in one emergency. You"re claimed to count on her instruments.

**Josaphat***: *It did bring earlier the inner 3rd grade in me, where it"s like, oh, girlfriend gotta stay up all night and also figure the end this math problem. Battison: carry out you have actually an really answer?

**Alex Appolonia:** Well, no exactly. We found a many of different answers come this brain teaser. However the whole point of these inquiries is to show how civilization think. Google no much longer asks these brain teasers, because they don"t predict just how well who would do at a job, however we want to have a tiny fun v it. Feel complimentary to permit us understand in the comments below more mind teasers friend would prefer to watch solved, and make certain you i ordered it to our channel, so friend don"t miss out on it.
