How long would it take, for all of the adults in the UK to build a 3 mile tall sea wall all around the UK?

Question

Assuming all adults and healthy. Working an eight hour day.

Just for entertainment.

Answer 1

Why just adults... get thosekids working .. they have too much time on their hands

Answer 2

I'm a UK adult and I wouldn't want to build a wall around the UK, even if it was just for entertainment!

Answer 3

You can count me out. I'm busy.

Answer 4

Well, the Great Wall of China took about 300 years,

so we in Britain can double that, we have tea breaks

strikes, bad weather, bad backs with time off,

public holidays, then it will go to private firms, not

to mention health and safety people putting up

extra scaffolding etc... need I say more?

Answer 5

39.56 years.  I saw the documentary on MTV the other night.

Answer 6

Difficult to calculate. we seem to get more adults arriving every day.

Answer 7

No idea but lets start right away,  what a blooming good idea!

Im just grabbing me trowel now, whose got bricks?!!

Answer 8

okay, population of the UK is 60Million.  Can't fine a breakdown of over18vs under 18 but did find that 15+ make up for 50M of that, so we will take a safe estimate and say 40M adults.

Next, the coastline is 11K miles long.

So that gives us 3636 adults per mile, which means each person would only have to do a 1 and a half foot section.

So, not very long at all

edit:

c**p, I mised the three mile tall part. who the h**l knows in that case. Nothing even close to that has ever been done in human history, so theres no way to tell.
