Don't need to calculate it

Just fill it with sand or water then measure it in terms of cups or
can sizes or make a simple tall box 3" or each side to determine volume. :thumbsup: bill

Thanks for the answers , but i'm in the process of making one . So i can't use that approach. The picture is of a previous vase with the same basic shape. I just wondered if someone had a ballpark idea of what the volume might be ....i have no experience with urns but i figured someone else might. Thanks.

 

Just knowing a little math you can just you a simple formula of a cylinder and that would... volume=pi*radius^2*height... So therefore your answer would be approx 397 in^3. You can convert this to ounces where 1 in^3 is equal to .55 ounces. So your answer you might be looking for is approximately 218 ounces your vase could hold. Hope this helps.

 

In the case of a tapered cylinder, averaging the major and minor diameters, will get you in the ballpark.

 

I agree easiest is to fill and measure.

To do it with math, you sort of have two parts: a standard cylinder of empty space, which is easy: radius of opening x pi(3.14) x height

and the volume of the curving bulges outside the cylinder, which requires calculus and I can't help you there!

 

That is incorrect. It should be the radius SQUARED x pi x height, exactly as fischer18 already stated.

 

If the bulge is at all regular, you'll get a quite accurate answer by just using the formula for a cylinder but with the diameter half way between the narrowest and the widest parts of the profile.

 

If Google urns will find a formular based upon body weight of person or pet.

 

I'm Going through this right now. As stated the correct formula is radius squared times pi times height for cubic inches. The volume required is approximately 1 cubic inch per pound. You can fill the vase with rice and measure how many cups then convert to cubic inches. 1 cup equals 14.64 cubic inches. I screwed up my math and made it too small so I made several smaller keepsake urns for the kids to keep or disperse her ashes where they think she would like.

 

Thanks guys , i really appreciate the input !!!!!

 

thanks for catching that Phinds. My bad.

 

Container volumes

Hi Guy,
Check out this site, it will give you formulas for any style container.
Hope it helps........good luck

It can be calculated exactly (or as close to exactly as you like) through some calculus and detailed drawings. Or you can just break it into a few sections and calculate the volume of those few sections then add them together. Break it into 4 sections and those 4 should be fairly easy to figure out. That's basically what calculus would do, except there would be infinitely many sections instead of just 4.

*edit* wow, just realized I replied to a two month old thread. I should get to bed. Night shift is taking it's toll on me I guess.
