Yes, there's a non-machinable surcharge of 20 cents over regular postage.
Try it out! Take the square of several (in this case small) integers, until you find one square that is less than 15, and one that is more.
144 square feet (12 X12) is normal for all except the master bedroom. Master bed room is more like 250 - 300 square feet.
"Still" implies that the original number is a square number. In that case, the answer is as follows: There is no number such that it is a perfect sqiuare and that the number increased (or decreased) by 10 is also a perfect square. And if you do not limit it to perfect square then every non-negative number is a square with the number that is 10 more also being a square.
1 if it is a letter and no more than 1oz in weight. You must add more postage for every added ounce. The answer also varies with the class of mail you are sending. Call your local post office for exact amounts.
Prime numbers have two factors. All square numbers (other than 1) have more than that.
Mail and stampage is based upon the weight of the mail. As long as the letter is still light, you shouldn't need more postage.
Yes, the shape can have an affect on the cost. Large 'flats' require a premium due to size. And square envelopes are considered 'odd' and will need more postage. Consult the USPS web site for specifics and current costs.
Yes, you would have to pay postage for stuffing envelopes, because it would cause the envelopes to weighh more than they should and shipping and handling goes by weight.
Padded envelopes are often used for mailing small objects that require a little more protection than a normal envelope but not so much that they require special wrapping and a box.
With self-sealing envelopes, all one have to do is to remove the protective tape from the flap and close the flap down for a secure seal. It differs from other envelopes in that it doesn't require glue to seal the envelope so it is more convenient.
The cost would depend on the weight of the parcel. Big envelopes cost more than small envelopes of equal weight. You probably should go to your post office to mail this.
One can find out more information about stuffing envelopes as a job by contacting the local Job Centre Plus. They will be able to provide contact information for genuine companies who require this sort of work.
The cost of your mail is all about the weight of the package. the more that it weighs, the more it costs. The shape of the envelope is not going to change the price at all
I know the post office has to hand process square sized envelopes. Their machine has a hard time locating the stamps location because of the envelopes size. I have mailed square envelopes a lot of times. If mailed within the U.S., it's $0.03 more than the standard $0.44. So it is 47 cents....that is- if it is the normal weight of a card or letter. If it's over an ounce, the price goes up.
Square EnvelopesSquare envelopes are subject to the $0.20 nonmachinable surcharge.As of May 11, 2009 a regular first class stamp is $0.44 so postage for a square envelope is $0.64Technically, the 6 1/4 x 6 1/4 size classifies the letter as a "Large Envelope" (smallest dimension > 6 1/8 inches), but since it is so close (1/8" !!) they may not enforce the higher Large Envelope rate.See the post office website for more information: http://pe.usps.com/text/dmm100/postage.htm
Number 10 envelopes are the classic business sized envelopes and can be found at most stationary stores such as Staples. The website, Graphic Focus has more information on envelope sizes.
The current postage cost for a USPS First Class Mail Letter (1 oz. ) is $0.49. Unless, the letter's weight is more than 1 oz. it is not more than that.
