# the volume of a grain of sand

Now let's try our hands at critical thinking and experimental design. I have a very simple question for you; what is the average volume of one grain of sand ?

Less than the universe and more than an atom.

That would depend on what you consider average is for grains of sand since they come in many sizes.

Exactly, with man helping to classify and collect them into lots.

When does a pebble stop being a pebble to become a grain of sand.

Answer 2 years ago

Apparently

In terms of particle size as used by geologists, sand particles range in diameter from

0.0625 mm(or^{1}⁄_{16}mm) to2 mm. An individual particle in this range size is termed a sand grain.Answer 2 years ago

So a pebble is a pebble over 2 mm.

Answer 2 years ago

Aparemtly although to be that's a big grain of sand.

Answer 2 years ago

I thought it was big also, but I did ask when a pebble stops being a pebble.

Answer 2 years ago

When it is in your shoe.

Answer 2 years ago

Don't matter what size it is, when it's in your shoe it's as big as a house.

Answer 2 years ago

When it starts being a rock.

Answer 2 years ago

Dude it's rock and roll.

Answer 2 years ago

Unless it was a stone to begin with. But then, Stones bring us right back around to It's Only Rock and Roll. Less than the universe and more than an atom.

about 6.2×10

^{−}^{11}(A medium grain of sand (0.5 mm diameter, 1.5 milligrams))Finding the volume of a sand grain:

The formula for the volume of a sphere is:

V = (4π/3)R

^{3},where R = radius of sphere.

R = 0.25mm = 2.5 x 10

^{-1}mm= (2.5 x 10

^{-1}mm)(1m/10^{3}mm)= 2.5 x 10

^{-4}m.(4π/3)R

^{3}~=4.18 x (2.5 x 10

^{-4}m)^{3}=

4.18 x (15.6 x 10

^{-12}m^{3}= 6.48 x 10

^{-11}m^{3}.sometimes I think I have far too much time on my hands.

Too much time on your hands? OK. Sure.

Barbados, California or Ben-My-Chree Beach on the Isle_of_Man sand ?

Answer 2 years ago

Came from google (of course) so I have NO idea what the parameters were. But I assume this is an idle question anyway.

Answer 2 years ago

I agree, especially for something that important to save the world....
