That means people can ride the London Eye at one time. One rotation lasts 30 minutes, so it can carry 1, people per hour. If the attraction is open from 10am to 7pm, the capacity is 13, people per day. Let's say it operates at two-thirds of its capacity on an average day, so 9, people go on the London Eye every day. Assume one toaster per household.
The average British household consists of 3 people. Given that the UK population is 60 million, there are 20 million households. Assuming a toaster needs to be replaced every four years, one quarter of all households are going to buy a toaster every year.
This puts UK toaster sales at 5 million per year. Assume that the diameter of a ping pong ball is 4cm. Because the balls do not tessellate, each ball occupies a volume of 4cm cubed. One cubic meter will therefore hold 25 by 25 by 25 balls, which is approximately 16, To calculate the volume of the aeroplane's fuselage we're going to approximate it as a cylinder.
There are ten seats, each 50cm wide, and two aisles, also 50cm wide, in a row. This gives our cylinder a diameter of 6m 0. Let's suppose there are 50 rows, covering an average distance of 1. This gives a length of 70m. We can now calculate the volume of the fuselage to be approximately 1,m3 27m2 multiplied by 70m. This can be filled with 30 million ping pong balls 1,m3 multiplied by 16, balls.

You choose the numbers, so pick nice round numbers that are easy for you to manipulate. Even if you just read a study that states that there are million inhabitants in the United States, no interviewer will flinch if you estimate the number of American inhabitants as million.
Video resumes are gaining in popularity on TikTok and elsewhere, so chances are you might be submitting one soon. If you're unsure how to go about preparing a video resume, here are five essential tips to set you on your way to success. For example, not even the brightest tone in the world can convince anyone that you mean well if you tell it with a frown.
How to Be More Interesting in Interviews Although not explicitly, hiring managers judge interviewees on how interesting they are. Today, we're very excited to release our complete Internship Rankings. This year, our Internship Rankings highlight the top programs in more than 30 categories. Just how important is law firm prestige? Acing Guesstimates. Published: Mar 10, Topics: Interviewing.
The best approach for a guesstimate or brainteaser question is to think of a funnel. You begin by thinking broadly, then slowly drill down towards the answer.
Let's look at this approach in context. Referring to our sample question, you know that you are looking for how many ping-pong balls fit in a airplane. The first thing you need to determine is the volume of the ping-pong ball. Your verbal dialogue might go something like this: Let's assume that the volume of a ping-pong ball is three cubic inches. To match the number of ping-pong balls in one cubic meter, you would need around 18 billion ping-pong balls….
But we can give you an idea by illustrating how it works with objects that might be more familiar. Or put another way, if you were to count them at per minute it would take more than 3 months to get to 18 billion. The number of ping-pong balls is calculated using the volume of a single ping-pong ball. There is no reliable source for the exact number. The closest would be, which states that it is 0.
To convert this into cubic feet we divide by to get cubic ft. The volume of the plane is about 4,, cubic feet ft. The s used by South African Airways can hold 24 standard pallets per flight. Sixteen pallets are in the front of the plane and eight in the rear. So one plane has room for 19, pallets or 1,,, pieces of cargo which weigh , million pounds.
