What is the volume of a golf ball?
The formula for determining the volume of a sphere is 4/3 * pi (3.1416) * 0.84^3. Calculating that, we can estimate the volume of an individual golf ball to be about 2.5 cubic inches. Now, coming to the bus, here’s where things may seem trickier. But fret not; simply use the size of a standard school bus for your calculations as a reference.

Ball Specs. Every golf ball that is manufactured by a leading golf ball company is tested to ensure that it does not have rule-breaking characteristics. The initial velocity of all balls is tested in a controlled environment. The speed of the ball at impact is measured, and if it exceeds the legal limit, the ball is not approved.

How do ping pong balls minimize space?
They minimize the space in between them by sitting adjacent to each other (similar to the way bricks are layered). Given that the ping pong balls can minimize some of the space in between them when they are poured on top of each other (in 3 dimensions), I estimate the space saved is ~25% more.

How many piano tuners are there in Chicago?
By dividing the number of pianos by the numbers of pianos tuned each year, you come up with the answer that there are ten squared, or 100 piano tuners in Chicago.
How to solve the Fermi problem?
This type of question is known as a Fermi Problem, and it can be solved by slightly overestimating and underestimating the figures using powers of ten with the assumption that they'll balance each other out in the end. To start you need to figure out the number of people living in Chicago. Instead of coming up with an exact number you can use 10 to the sixth, which equates to 1 million, to represent the population (the actual population of Chicago is just under 3 million, but we’re estimating!). Next, you need to estimate what portion of the population owns a piano. If it’s one out of every 100 people, that’s represented by 10 to the power of negative two, which when multiplied by ten to the sixth equals ten to the fourth (this may be starting to look complicated, but using the power of ten is actually how mathematicians are able to keep big numbers manageable).
How to weigh an elephant without a scale?
You can fill a large cylindrical glass vat with water not quite to the top, place a boat in the water and mark the water level. Then you put the elephant in the boat (which is probably harder than just buying a scale) and mark the new water level. Measure the difference between the two marks and with a little math you can easily calculate the weight of the elephant. Let’s hope that literally having to do this isn't part of the job description.
How many times do the hour and minute hand overlap?
The only time the minute and the hour hand come together perfectly on the hour is at 12 o’ clock. After that the overlap occurs slightly after 1:05, then slightly after 2:10, etc. By the time the minute hand catches up to the hour hand the eleventh time, the hour hand has had enough of a head start that they don’t cross paths until 12 o’ clock, thus beginning the second twelve-hour cycle of the day. This means that there are only 11 times the two hands overlap every 12 hours, so they come together a total of 22 times during one day.
Can round manhole covers fall through?
As we’ve explained here before, round covers are incapable of falling through manholes no matter how you position them. The ‘lip’ lining the rim of the opening ensures that the cover is always wider than the hole. Covers that are square, rectangular or oval in shape risk falling through if they’re inserted diagonally.

Now that you know the dimensions to use as reference points, let’s crunch the numbers, shall we?
Answering Some Other Questions
Let’s have a look at the frequently asked questions on this. Do you have them in mind as well?
Last Words
We often have to face tricky questions that seem very hard to answer on first listen. The query of how many golf balls fit in a school bus is one such question. But while it seems super hard to answer at first glance, it is actually quite straightforward if you just figure out the science behind it.
