People have been known to carry around tennis balls in their pockets. In fact, they were sometimes called “pocket full of posies.” One might ask themselves how many tennis balls would fit inside a 747? This is a question that has people keep asking, and with different numbers of people answering this question, it makes for an exciting discussion. Approximately 688,705 tennis balls can fit in a Boeing 747. In this blog post, we will explore how we obtained this answer.

**What Is A Tennis Ball?**

A tennis ball is a smooth, solid sphere that weighs between approximately one and three ounces. The world’s most common recreational balls are yellow in color and about seven centimeters (two-and-a-quarter inches) across. Tennis balls also come in at least 31 different colors, such as pink, blue or green, with each differing slightly from the others. Tennis balls can be solid rubber or a hollow core wrapped in rubber.

**How Is A Tennis Ball Different From A Golf Ball?**

They are both balls, but the differences between tennis and golf ball are pretty significant. The biggest difference comes down to size. Tennis balls range from about 30 mm in diameter, while a standard set of golf balls will measure at least 42mm – which means they can hold more air than their smaller counterparts.

The type of material used makes it easier to grip and control the tennis ball. The type of material used makes it easier to grip and control a golf ball as well, but they don’t come in different sizes – just one round design that’s perfect for driving.

**How Is A Tennis Ball Different From A Ping Pong Ball?**

A tennis ball has a fuzzier outer layer. The main difference between a tennis ball and a ping pong ball is that tennis balls are larger than ping pong balls because there is air inside them which allows them to be able to bounce higher than other types such as those used in table tennis. This makes this ball perfect for playing tennis because it will enable you to be able to hit balls from further away.

Another difference between a tennis ball and a ping pong ball is the weight. Tennis balls are much heavier than ping pong balls because they have air in them, which adds to their weight. This makes tennis balls not ideal for playing table tennis or when you need your ball to come back after being hit. On the other hand, one of the best things about a ping pong ball is how fast it can be thrown and come back at you after being hit.

There is also a difference in the circumference and size of each ball as well as how much air is inside them. The tennis ball has a larger circumference compared to ping pong balls which measure about two inches more than it does around its middle point, whereas the ping pong ball only measures one inch tall.

**What Is A 747?**

The Boeing 747 is a wide-body commercial airliner and cargo transport, often referred to by its original nickname, Jumbo Jet. It has a typical capacity of over 400 passengers but in some configurations up to 550 seats. The hump created by the upper deck has made it one of the most recognizable aircraft ever built and resulted in its nickname “Queen of the Skies.”

The 747 was expected to become obsolete after 400 were sold, but it exceeded critics’ expectations, with production passing the 1000 mark in 1993. By October 2011, 1377 aircraft had been built or ordered, including 555 -400s and 102-300s for commercial use.

The 747-400 has a maximum takeoff of over 850,000 pounds (390 t) and incorporates four wing-mounted engines. The interior cabin width is 11 feet (132 in; 340 cm). Its overall length is 215 ft., seven inches (63.90 m), and the wingspan is 195 ft., nine inches (59.75 m).

With a volume of about 31,285 cubic feet, the 747-400 can accommodate 416 standard pallet positions or 150 to 168 passengers in an all-economy class layout and 74 fewer seats when equipped with mixed class seating up to around 550 passengers depending on how airlines choose to configure the aircraft.

The 747-400 can accommodate 16 LD-III, 36 carts of cargo, or up to 80 passenger comfort units (PCU) containers. Via a GDS interface and with software modifications, airlines could also have the option in the future for higher maximum takeoff weights by loading heavier PCUs into lower deck bins which can also be used for additional cargo.

**How Many Tennis Balls Fit In A 747? **

The volume of the tennis ball is 47.916πcm^3. Finally, after dividing the volume of the airplane by that of the tennis ball, we get at 688,705. Therefore, we can fit about 688,705 tennis balls in a Boeing 747.

To answer this question, you need to know the dimensions of a standard size tennis ball and also the dimensions of an airplane. Well, if you have ever seen a Boeing 747-400ER stored at an airport, you may notice that it is about 67 feet tall and 210 feet long with a wingspan of 195 feet.

Now let’s talk about the size of a standard-sized tennis ball. What is the size of a tennis ball? The standard size tennis ball is about 27mm in diameter and weighs approximately 62 grams. Now that you know the dimensions of both things, we can begin to answer your question! First, let’s calculate how much space one single tennis ball takes up.

The volume of a sphere is calculated by multiplying three times π times the radius squared, all divided by six times the radius. To calculate this, we first need to find the radius of a tennis ball. One can use an online calculator, or one could take out a ruler and measure it themselves. For the volume calculation to be as accurate as possible, you should take several measurements and then average them all together to find the radius.

Let’s say that the radius of an airplane is 1 m and its length is 33 m…

*assuming the airplane has the same height as a typical office floor

400 seats in an airplane with ten seats a row which gives us 40 rows, and adding another ten rows for pilot and toilets, we get to 50 rows

* 2 feet which give us 100 feet or 33 meters

The airplane volume: 103m^3 or 33πm^3 or 33mπcm^3

The volume of a sphere is = (4 πr3)/3; therefore, the volume of the tennis ball would be 47.916πcm^3.

Finally, after dividing the volume of the airplane by that of the tennis ball, we arrive at 688,705. This means that approximately 688,705 tennis balls can fit in a Boeing 747.

**How Do You Answer Brainteaser Interview Questions?**

“How many tennis balls fit in a 747” is an example of a brain teaser interview question. Brainteaser interview questions are a unique way for employers to see how you think on the spot and outside of your comfort zone. These questions may seem intimidating at first, but they are a great way to test how you think on your feet.

Here are some other examples of brainteaser interview questions:

**Question:** **How would you weigh planes without scales? **You could use the weight capacity of each individual airplane and then compare them all together using that information. Some may be able to hold more than others, so you would need to find out which planes could accommodate the most weight.

**Question: If it took eight men ten hours to build a wall, how long would it take four men to build it?** You can take the amount of time it took for eight men and divide that by four to figure out how long a wall will take.

**Question:** **If manhole covers are round because that’s the only shape they fit in, what is the shape of an egg?** You could answer this by saying that you don’t know the exact shape of an egg because it’s not essential. The point is, manhole covers are round to make sure they can open and close quickly.

These are just some examples of how you can answer brainteaser interview questions. It’s important not to get too nervous because it will show in your answers, and employers hate when people are unconfident! Remember, if an employer asks you a brain teaser interview question, you have been prepped for it. You have gone over the types of questions, so this should be easy.

**Conclusion**

A 747 can carry up to 688,705 tennis balls. That’s a lot of hits! It must take more than a few hours for the whole plane to be filled with this many tennis balls. If you’re ever in an airport and want some fun math practice, try guessing how much time it will take for that jet bridge or baggage carousel to spit out all those balls – it might just give you something interesting to do while waiting on your flight home.
