You couldn't say with that level of accuracy how many pebbles there were without counting every single one. But anyone who has been to Brighton beach would be able to estimate it to the nearest order of magnitude. I've never been there before, but lets say the pebbles on the beach stretch for 500m, 20m across, 1 cm deep (on average). Then thats a volume of 100 cubic metres. An average pebble might be 5 cubic centimetres which would give you in the order of 20 million pebbles.

I am looking at the nearest dozen by torchlight. Fortunately all the pebbles are of the same size so I can tell you that there are one dozen pebbles in a line next to the nearest dozen, plus one at each end of the nearest dozen, which makes 14 in all.

How big are the pebbles? If Brighton Beach is sand only, then there are zero dozen pebbles.

who rounds to the nearest dozen ????? ( must be the new donut/bagel/egg system,,,, base 12)
where is Brighton Beach ... England, Brooklyn or a hundred different places named Brighton...
If you define pebble,sand is not in pebble forn, therefore no pebbles on the beach (Unless you drag them in from the parking lot)

Why round to the nearest dozen ?
I would have thought that weight rather than count was a better way of measuring.
You coul then of course round to the nearest stone.

that is impossible to say because with each rise and fall of the sea pebbles are brought and removed. how far out does a beach go?

This ridiclous question cannot possibly be answered!
How do you define 'Brighton Beach'? Even if you get a precise definition, no one is going to dig down to the bedrock to count them!

As many pebbles as the beach wants there to be. GOSH!

How on earth will you verify the answer, or choose the best answer?
