Maths volume question help req..please!
 

Can anyone tell me how to work out the liquid volume of a flat sided tank, for example, if the tank was 18x12x12(inches) this equates to 2592 cubic inches, or 216 cubic feet....hope thats right! What I need to know is the formular for working out the liquid capacity. Thanks in anticipation.

Nearly
 

2592 cubic ins = OK but it is 1ft x 1ft x 1.5ft = 1.5 cubic feet.
But you are supposed to have gone metric by now!!

Hello Dave,

Been wondering how you are getting on with the Enfield tank. Have you flattened it given the question?

Regarding your question you are nearly right but you have the units wrong. If you have a 12"x12"x18" volume you are correct in saying this is 2592 cubic inches. But you can't just divide this by a factor of 12 to the cubic feet measure - you need to divide it by (12x12x12). Therefore your answer is 1.5 cubic feet.

Hope that is clear and all is well with you.

Hi guys, thats why I posted! so assuming I have, as you confirmed got the cubic inches right....then how much liquid in litres will it hold and how do I work out how much liquid any other size will hold?


Matt, the tank as been painted and had one coat of lacquer applied, it is now with a mate to have 'one off' transfers applied then back to the sprayers for pinstriping and more lacquer. should be on the bike by early next week...can you please pm your email address....cheers

Litres is a metric unit .. as it is easy to work out in metric

1 litre = 1,000 cubic centimetres....

so
18" 18x 2.54 = 45.72cm
12" 12x2.54 = 30.48cm


45x 30 x 30 /1000 = 42 litres.

Is that air litres or liquid litres? And dont forget that petrol and water litres are different.






Just kidding.

Go metric young man, far easier than converting cubic inches of water to gallons, quarts, pints, fluid ounces, drops, drips and micro drips.

2592 Cu inches is 74.9 pints (UK)... which is a decent party in my book...

Use metric
 

For once I'd say use metric.

• Measure all the lengths in centimetres (they've been done above).
• Mutliply the lot together to get the volume in cubic centimetres
• Divide by 1000 for litres.

Simple.

Which is heavier - a ton of feathers or a ton of coal?

are you measuring at the top or the bottom? and is that African tons or UK tonnes?

You could of course fill the tank and measure what goes in

depends which one is being dropped onto you.

..........and which planet you are on:rolleyes:

since all your measurements are 'outside' of the container, you failed to factor in the volume of the container taken up by the interior plastic. :oops2:

I go with Silver G - fill it up with a known quantity (as in, count them liters). :thumbup1:

Much simpler then that math crap. :thumbdown:

As a question of grammar, shouldn't "nonexistant" have a hyphen?
Also, "dont" have an apostrophe?
Plus aren't the words in the brackets redundant as surely when saying "some English people" intrinsically means that others don't fit into that category?

It seems that my pedantic pill is working, sorry.

Hi Mark
The _rick who is giving the English lesson is not worth a _ank, I would rather not reply to the _unt as he tries to cause trouble and half the time is only trying to boost his 'posts counter'. Ask Grant or Susan how many times this _rick as been either banned or been on 'moderated user' I am sure Ol' big boots being so good with English can sort out the missing letters himself. Just watch how many replies he makes in this thread.
