A stack of papers.
If it is sheets of paper in reams (500) = 1 pack
There are typically 500 sheets of paper in a ream.
500 Sheets in a Ream of Paper
500 sheets is typically referred to as a ream of paper.
The width of a pack of 500 sheets of paper can vary depending on the paper size and thickness. However, for standard letter size (8.5 x 11 inches) paper, a pack of 500 sheets would typically have a width of about 2 inches.
The usual number is 500, but occasionally some reams have 480.
Usually a group of paper is called a ream. This would be around 500 sheets. Otherwise it is referred to as a stack of paper.
A Ream is a measure of the NUMBER of sheets of paper (500 sheets) How thick that would be will depend on the weight of the paper. Heavier paper is thicker.
70gsm means that 1 sheet of A0 (16 sheets of A4) should weigh 70 grams. Therefore assuming we are talking about 500 sheets of A4 paper then it will weigh (500/16)*70 grams or 2187.5 grams.
500 sheets = a ream of paper.
500 sheets of 80 gsm A3 paper would weigh approximately 4.8 kg.
To find the thickness of one sheet of paper, divide the total thickness of the pack (50mm) by the number of sheets in the pack (500 sheets). Each sheet of paper would be 0.1mm thick.
