One, they print it out at the post office for how much you need (this week).

If it weighs up to one ounce and is rigid and not extra thick you can mail it for 88 cents ( two first-class stamps). If it weighs 2 ounces the cost is $1.08. If it heavier or thicker, it will cost more.
That depends on what it weighs and where it's going ... not so much on its size. (It could also be related to the denomination of the stamps.)
If you envelope weighs less than one ounce, it will take one forever stamp or one current first class stamp. If the letter and envelope weigh more than one ounce, the number of stamps will depend on the weight and the denomination of the stamps.
As of June 10, one ounce of first class mail is 44¢. Every additional ounce is 20¢. So, a six ounce envelope would cost $1.44 to mail, or four forever stamps.
Depends on a few facts. 1.) The weight of the letter combined with the weight of the envelope! 2.) The shape of the envelope. 3.) The denomination of the stamps......i.e. $0.01 stamps, $0.05 stamps, $0.42, etc. (all USD). 4.) The chemical composition of your saliva (spit) for licking the envelope. For example, if a #10 envelope weighs less than 0ne(1) once, the cost would be $0.42 USD. The number of stamps (you asked "How many") would be 42 if you used $0.01 stamps, all the way up to only 1 stamp if you used a $0.42 stamp This site will explain everything from size to weights. http://www.usps.com/welcome.htm Good luck!
The A4 envelope weighs about 5 grams
The number of stamps needed for an envelope depends on the weight and destination. The weight limit for a standard USPS First-Class Mail envelope is 3.5 ounces. For an envelope weighing 12 lbs, you would need to use a different shipping method, such as USPS Priority Mail or USPS Priority Mail Express. The specific number of stamps required can be calculated using the USPS postage rate calculator or by visiting your local post office.
An empty business envelope weighs 1 gram.
Just one first-class stamp, unless the envelope is large, or weighs more than 1 ounce.
A buffalo ways like 2000 pounds when they are full grown. A moose weighs about 700 pounds when they are full grown. So a buffalo weighs more.
