The cost to mail a manila envelope will depend on the size of the envelope and the weight of the envelope. The average cost to mail a manila envelope that is 8"X11" is about $2 if the contents weigh less than one pound.
You will need postage for the weight of the envelope (probably 2 ounces, for 4 sheets of paper in a 10x13 envelope), plus a surcharge for the size of the envelope. Best guess: $1.19 for first class mail within the United States, as of Feb. 2014.
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.

I went to the post office today (1/07/11) and one manilla envelope (without the metal fastener) with one piece of paper in it cost $.88 - it weighed 1 ounce. The second envelope contained 8 pages and weighed 3 ounces and cost $1.22. So by my calculations the envelope alone weighed about an ounce and 8 sheets of 8.5x11" weighs 2 ounces. Hope that helps.

The answer is an envelope. It contains a letter.
One sheet of paper weighs bout 1/6 of an ounce. The cost to mail 30 sheets of paper may be estimated using a scale. The post office can give the exact amount shipping will cost based on the weight, the method of shipping, and the place the paper is being shipped to.
