sorry.
i came on another problem. the volume of a tank is 2.15 x 1.^5 cm^3.
how many gallons of water will it take it to fill it up?
how do you do that?
maybe im wrong or wrote the correct answer differently...
i put that there is 4.96 x 10^-7 tons in 4.5 x 10^2 kg. is that right?
and for a drive way that measures 20ft by 30ft, how much area does it cover in square mL... but i think its mm since the answer is 5.57 x 10^7. but even so..... i got 5.57 x 10^11...
i need help to see if im right or which is which...
Hello,
(I know the tons in kg, I hope you were speaking of "short tons")
So
So I don't think your answer is right.
Hmmm if L stands for Litres, then it is not possible since L is for volumes, not areas !and for a drive way that measures 20ft by 30ft, how much area does it cover in square mL... but i think its mm since the answer is 5.57 x 10^7. but even so..... i got 5.57 x 10^11...
1 foot=304.8 mm. (we know that 1 foot=30.48 cm and 1cm=10mm)
So 20ft x 30ft=(20*304.8)(30*304.8) mm˛=5.57*10^7
Okay.
I think you have a problem with the cm, mm, etc... meanings.
The standard unit is m (for meter)
Here is a table of correspondance :
remember that the same letters in front of m apply to litres and grams.
We know that 1 gallon = 3,78541178 litres
Now, remember that 1L=1 dm^3, that is to say
or
Try to do it
No, it is dm^3
Edit : I must say I cheat a little since I'm in a country where we use these metric systems. On the contrary, it's a real difficulty if we travel to the USA
Well The US Keeps Saying That We Will Switch To Metric...Its Just Sad To See That They Keep Saying That
well the original problem is how many tons are there in 4.5 x 10^2 kg? and the answer is 0.496. but what i did was from 450 kg and convert to grams, to lbs, to tons... and i guess my answer is wrong...
i think my problem is that i quickly read the suffix of the unit and assume that is the number without reading what unit is below or above. i accidently put 1000 mm = 1 cm
and well its for chemisrty... and he only limits us to the units he gave us... but i will try
Merci Beaucoup Mademoiselle Moo
And I'm sure it's dm not cm. If you take dm, you'll get the correct answer you're given
I don't know which tons you use...
There's a ton in my country we use as being 1000kg, but when i looked up in google, i found that a "short ton" is 904 kg.
then you should get the correct answer now !i think my problem is that i quickly read the suffix of the unit and assume that is the number without reading what unit is below or above. i accidently put 1000 mm = 1 cm
it's 1000mm^3=1 cm^3
You are very welcomeMerci Beaucoup Mademoiselle Moo
Oh by the way, look at here for the powers of the meter : Metre - Wikipedia, the free encyclopedia
Litre - Wikipedia, the free encyclopedia
Wikipedia explains it wellOne litre is equal to 0.001 cubic metre and is denoted as 1 cubic decimetre (dm3).
