it's a trick question. any idiot can apply a formula. any idiot can memorize ρ=m/V - the formula was provided with the problem in order to fool people who rush to answer the question incorrectly thinknig they are geniuses because they divided one value by another, whoopty fucking doo.Quote:

That's why there even was a fifth option of "no answer", which is the correct answer.
even when juji does the sums backwards because he reads them backwards he still gets the answer right... if that was the way it was written.... which it isn't but that actually isn;t a reflection on his maths ability... juji is VERY good at maths.
dyslexia has nothing to do with intelligence... it's just a tendendcy of the way the brain works and unfortunately most things are set out in a way that is not dyslexic because dyslexia is more uncommon and it's more normal not to be dyslexic... it just makes it more difficult for someone with dyslexia to learn writing skills because of a tendency to process things in a way that seem "backwards" to people without dyslexia.
Take in account that juji is also deaf and English is not even his first language... then it's plain to see he is actually highly intelligent... he just struggles to contruct sentences in written english without getting the gramma a bit mixed up. I doubt reading any of you backwards redneck intellectually inferior fuckatrd posters posts has been of any benefit to his development of written english... hell he still writes better than half of you.
no you were wrong and it wasn't a trick questionQuote:

so in fact you are wrong again, a mass does not have to be solid to work out its density you moron.
Juji was correct. And you are STILL making an idiot of yourself.
everybody who answered is intelligent. i know juji is intelligent, i know maks is too, and i even know you are intelligent in spite of yourself. most intelligent people will still flub that question because they see what appears to be a simple problem and don't take the time to stop and analyze exactly what it's asking before they rush to solve it.Quote:

I found the topic and question...
The answer is b.Quote:

Instructions
Determining Density for an Object of Regular Shape
1
Weigh the object using a scale or balance. Write down the result and note what units are being used: grams, kilograms, ounces or pounds.
2
Measure the dimensions of the object with a ruler. For a cube, you need only measure one side, because all sides are equal in a cube. For a rectangle, measure width, length and height. For a sphere, measure the diameter or the radius. For a cylinder, measure the radius of the circle face and also the length of the tube. Keep in mind that if your object is hollow, this method will result in an overall density including the air inside, not an accurate density of the material itself.
3
Calculate the volume of the object. For a cube or rectangular object, multiply the length by the width by the height. For a cylinder, multiply the radius of the circle part by itself (square the number), then multiply that result by pi (3.14), then multiply that by the length of the cylinder. For a sphere, cube the radius of the sphere (radius times radius times radius), then multiply that result by pi, then multiply that result by 4/3 or 1.333. Regardless of the shape, your result is in cubic units, probably either cubic inches or cubic centimeters, depending on what type of ruler you used.
4
Divide the mass by the volume to get the density. The units of density will be the same as the units you used; if you measured in centimeters and weighed in grams, the result is grams per cubic centimeter. If you measured in inches and weighed in ounces, the result is ounces per cubic inch.

The volume of material used to construct the tank is BQuote:

Read the question. Which volume is it asking you to find?
The question is asking this Bob
what would be the volume of a gas tank
You fucking idiot
repeat again for the special needs maths kids
"what would be the volume of a gas tank that has a density of 10 kg/liter and a mass of 3
kilograms?
density = mass/volume
a. 30
b. .3
c. 3
d. 15
e. no answer"
e
you finally get itQuote:

Sorry but if you answered anything other than b then you are wrong in this question.

volume is inside the tank... makes no difference what the tank is made of... it could be made of cucumbers, steel, plastic.... doesn't matter
it is asking for the VOLUME and gives you the density and mass in order to figure that out. It actually gives you all the information you need to work out the VOLUME.
Juji and all the others who answered b were in fact correct. You have a comprehension problem with the actual question. The flaw does not lie in the question or the FACT that the answer is b. The flaw lies in your lack of comprehension of the question posed. Sorry but you should stop digging in the hole you've made yourself on this one. ANd trust me, I used to be a teacher. Not only that but it's been confirmed by not only Lexi who posted the question but by some other pretty capable mathematic minds. WHatever the fuck else you are doing to the question doesn;t change the FACT that the answer to that question is b.
This thread makes my head hurt.
SOMETIMES bob
understanding what the question is actually asking is the hardest part... for SOME people.... ok what the hell.... for stupid people :P
The volume displaced by the contents of the tank is always less than the volume displaced by the tank itself.Quote:
