Google is known for asking incredibly difficult questions of its job seekers. Business Insider recently compiled a list of the 15 hardest questions (answers can be found here). Among them: Explain a database in three sentences to your eight-year-old nephew, why are manhole covers round, and how many piano tuners are there in the entire world?
One particularly vexing question: How many golf balls can fit in a school bus?
How would you solve it?
A clever reader's response, which begins:
I figure a standard school bus is about 8ft wide by 6ft high by 20 feet long—this is just a guess based on the thousands of hours I have been trapped behind school buses while traffic in all directions is stopped.
That means 960 cubic feet and since there are 1728 cubic inches in a cubit foot, that means about 1.6 million cubic inches.
I calculate the volume of a golf ball to be about 2.5 cubic inches (4/3 * pi * .85) as
.85 inches is the radius of a golf ball.
