litres to box size

[damianl]

just say i have a driver needing a box volume of Eg. "1.53 Litr" how do i work out the dimensions. im new to this have only ever used kits.

1 litre is 10cm^3. You can adjust the individual dimensions to suit.

thanks!!

No. Nono...

1 litre is 1000 cm³ or 1 dm³ or 0.001 m³. That is, a cube with the side 1 dm = 0.1 m = 10 cm encloses a volume of 1 litre.

Take the size in litres, multiply by 1000 and then take the cube root. That gives you the internal dimension in cm of a cube the right size.

If you take that number and multiply by 1.618 and divide it by 1.618 you get the dimensions in cm for a classic golden ratio box.

I will leave other shapes as an exercise

A cubic foot is a three dimensional area of space bounded by the dimensions of one foot by one foot by one foot.

.....soooooooo

A cubic litre has to be an area of space bounded by the dimensions of one litre by one litre by one litre.

Seems quite logical yet that doesn`t seem to work.

Coming into this from being comfortable in the antiquated Imperial system I found it impossible to wrap my mind around this, so I stick with building my cabinets in inches and foots. When volume is defined as cubic litres I have to de-convert into cubic foots. All this converting back and forth is a royal pain down around the cubic hairs.

I just read the question again and realized the answer is quite simple.

One and a half litres? That means they want you to make the cabinet out of a used beverage container.

Regions, yes, but an area refers to 2-D bounded surfaces. "Space" usually means 3-D. and is suitable as a volume. Every litre is approximately 60 cu. inches. or 1000 cubic centimetres.

take your volume in cubic centimetres and take the cube root of it. Times that value by:

[sqrt(5)+1]/2, and also by [sqrt(5)-1]/2

there's your dims, if a golden rectangle is desired for an enclosure (as Dave pointed out, the numbers are close to 1.62, and .62 respectively).

Those will be really tiny enclosures:
7.1cm X 11.5cm X 18.6cm

3-D space has `Regions`, not areas. I stand corrected. Thank you Nanook. It is late and my 2-D excuse is that I`m feeling quite zoned by now after a long day...

That is going to be an object in 9 dimensional space...

A liter is a volume unit, Like a gallon (=0.16 ft^3).
