The standard size of a postage stamp varies by country, but in the United States, a typical postage stamp measures approximately 24 mm by 36 mm. Other countries may have different dimensions, but many stamps fall within a similar range. It's always best to check the specific guidelines for the country in question if precision is necessary.
Say your post stamp is 30mm lengthways, it would then be 0.00003km.
cubic centimeter
If you have a length of 25 mm and then 12 mm it makes a length of 37 mm.
If the length is in meters (all the other measurements are in millimeters but if the length were also mm that would be a short post...)The volume of the square post in cubic centimeters is:4 * 9 * 1 * 340 = 12240the density of much construction steel is around 7,8 g/cm3So 7,8 * 12240 = 95472 grams or 95 kilogramsYou probably do not want to carry that by yourself
