You have helped me before I know you can now.

jdoe0001 · Answer

well, the lawn is 24 feet wide and 25 feet long, how many square feet are in it?
well, 24 x 25

each square foot will hold up to 1150 snowflakes in 1 minute
so in 60minutes, they'd hold 1150 x 60

Sorry, its 24x20

jdoe0001 · Answer

oh yes, shoot, I keep making those darn typos, yes, 20

jdoe0001 · Answer

so the how many square feet are there?   well, 25 x 20

amtran_bus · Answer

I just lost myself.  Wait a sec... 
It is 20x24
So 1150x60x480?

jdoe0001 · Answer

lol

amtran_bus · Answer

Then the mass of one flake is 1.90 mg

amtran_bus · Answer

So 1.90mg is 00000190kg, right?

jdoe0001 · Answer

once  first you get the amount of square feet
then how much they accumulate per hour
one times the other is how much snoflakes there are

to find the weight in kilograms, get the product of those 2 above and divide by 1000
1kg = 1000g

amtran_bus · Answer

But the thing says a flake has a mass of 1.90 mg?

jdoe0001 · Answer

yes, so pretty much is saying it has a mass of 0.0019 kilograms

amtran_bus · Answer

I guess i need coffee.  I thought the difference from a mg to a kg was 6 decimal places.

jdoe0001 · Answer

hhehe, man you're correct, yes, I'm mistaking grams to mgs, yes, it'd be 1,000,000 mg to 1kg

amtran_bus · Answer

Pheww.  lol.  Let me see if I can work it out.

amtran_bus · Answer

I got 62.93.

amtran_bus · Answer

kg

amtran_bus · Answer

What do you think @jdoe0001

jdoe0001 · Answer

yeap, is what I got
480 x (1150 x 60) => 33120000 * 1.9 => 62928000 mg
$\bf \cfrac{62928000}{1000000} = 62.928$
