Okay, so I saw this question online the other day that got me thinking: how many tennis balls can you actually fit into a limousine? Sounds crazy, right? But I was super curious, so I decided to give it a shot and figure it out myself. I mean, how hard could it be? Turns out, it’s a bit more complicated than you’d think.
First things first, I had to get the measurements of a limousine. I didn’t have one lying around, so after a bit of searching online, I found that a typical stretch limo is about 5 meters long, 1.8 meters wide, and 1.5 meters high. That seemed like a good starting point.

Getting the Volume
Next, I needed to figure out the volume of the limo. I remembered from school that to get the volume of something box-shaped, you just multiply the length, width, and height. So, I did 5m 1.8m 1.5m, which came out to 13.5 cubic meters. Alright, we’re getting somewhere.
Then came the tennis balls. Now, I know a tennis ball isn’t a perfect cube, it’s a sphere. There was some math thing about calculating the volume of a sphere, but I just looked up the average volume of a tennis ball online. Most sources said it’s around 4 cubic inches. But wait, the limo’s volume was in cubic meters! I had to convert one of them.
Meters and Inches…Yikes
Honestly, the conversion was a bit of a pain. I used one of those online converters and found out that 13.5 cubic meters is about 823,827.9 cubic inches. Man, that’s a big number!
So, now I had the limo’s volume in cubic inches and the tennis ball’s volume in cubic inches. The next step seemed obvious – just divide the big number by the small number. 823,827.9 divided by 4 is roughly 205,956.97. Boom! We have an answer.

- Limousine Volume: 13.5 cubic meters (or 823,827.9 cubic inches)
- Tennis Ball Volume: 4 cubic inches
- Initial Calculation: 823,827.9 / 4 = 205,956.97
But It’s Not That Simple
But then I realized, you can’t just cram tennis balls perfectly into a space. There’s going to be gaps, right? Those spheres don’t fit together like perfect little blocks. Plus, I hadn’t even thought about the seats, the weird shape of the limo’s interior, and all that stuff. I found some info online that suggested the best you could pack spheres into a space is about 64% efficiency.
The Real (Maybe) Answer
So, I took my initial number, 205,956.97, and multiplied it by 0.64 to account for the packing efficiency. That gave me around 131,812.46. I figured you can’t have a fraction of a tennis ball, so I rounded it down to about 131,812.
Final Calculation:
205,956.97 0.64 = 131,812.46, which I rounded down to 131,812.
So, after all that, my best guess is that you could fit around 131,812 tennis balls into a limousine. But remember, this is just a rough estimate! The actual number could be higher or lower depending on the exact limo, the size of the tennis balls, and how much time you wanted to spend trying to perfectly pack them in there. Still, it was a fun little experiment. Maybe next time I’ll try it with ping pong balls!
