REAL math, just for FUN

More than I can carry

Just guessing off the top of my head....120 lbs

I’ll post the answer in about 15 minutes :)

It’s not 120lbs, sorry

<20

If you were registered, I’d give green for that

I'm to heavy...

Can't get a woman huh?
Inceltard

Maybe if the water was from Flint ..

Cubic inches in US gallon = 231

Find volume of pipe....

Radius X Radius X Pi = 28.26 square inches
Length of pipe into inches = 360 Inches
Volume of pipe = 10,173.6 cubic inches

Pipe volume / gallon volume = 44.04 gallons

Gallon of water weight = 8.34 pounds

Total weight of volume of water = 367.30lbs.


The answer at work was 350lbs.

Man, I could tell you stories.....

it would be 30ltrs each litre weight equals 1 kilo



so weight would be 30 kilo

my mistake - I think its 60 kilo not 30 simply because a 2ltr bottle of pop is just about a foot and therefor would be 60 not 30

1 litre of water weighs exactly 1 kilogramme

My math says it would be 166 liters, but that’s with using US gallons.

Which is also 166 kilos.

The metric system is weird....

length x radius squared?

That heavy huh? damn....

And pi

R x R x Pi = area

Length x area = volume

78.

It's what came to me.

Close. :)

I haven’t a post from you in a while. I see your avatar is ready for the holidays :)

Wow that's cool cause I totally suck a math. lol

Well I post all the time... or did you mean to you personally?

Cause I have no idea who ya are. People seem to like to have many different names up in here. lol

It's all good tho. I prefer to just stick with one account myself.

But that's just me.

I sure do hope you have a wonderful evening!

*cha cha cha

Nah, I’ve posted here forever, just recently upgraded from another member (a real nice girl :) )

I just meant you, I haven’t seen you post anything recently. Your avatar is unique, so I know I haven’t seen you in a while.

In any case.......

cool but, I wish you would have specified the 6" round was radius.

Could have been diameter or circumference for all we knew.

Well hey that's cool!

Thanks for the compliment too.

That is very nice.

+1

If I knew radius, I would say....

6" * 3.14 * 2 * 30 = roughly 100 cubic feet of water?

100 * 60lbs = 6,000 lbs of water

my rough math in the head

I thought it was implied clear enough?

6” round pipe.

Sounded good to me.

Roughly 45 pounds. 1 gallon of water weighs about 8.3 pounds.

Alright, I can see where you’re at.

I was the guy at work who figured this out, and my boss was both impressed and upset. Impressed I was right, and upset he was sooooo wrong. We had a cart with a 400lbs load rating, and I said it was fine to drain the 30’ pipe into, but he was going crazy and didn’t believe me.

Anyways, for next time, for rough math....

A gallon is 231 cubic inches, but round it to 250 for easy math

Pi is 3.14, but round it to 3 for easy math


This is kind of math is easy to do, easy to remember. Helpful if you got to fill a pool and want to guess how much water you need, or if your filling in a large hole with dirt.

GREAT JOB!!!!

By weird you mean logical and awesome right ?

Just hard to get used to.

Celcius too. If you say it’s 39c outside, I’m gonna have to think for a minute to figure out how hot that is.

Americans just have no concept of metric shit.

I deal with imperial and metric at work, and when it comes down to .005 microns, I still gotta figure out how many thousandths of an inch that is.

I started with 6" around to be the circumference

2(pi)r = 6
(Pi)r =3
r = 3/(pi)

Area = (pi) [3/(pi)]^2

Now I have the area in square inches. Multiply by length...

If I were playing with paper and pencil or my NSpire/TI-89 I'd convert to metric to make the conversion to weight easier.

I do a lot of math too.
