As specified by the International Organization for Standardization (ISO), based in Geneva, Switzerland, the size dimensions of A3 paper are 297 by 420 millimeters (11.69 by 16.54 inches).
Take a piece of paper and cut it in half (anywhere will do) and you will have two pieces of paper - and your original piece of paper has changed shape.
tearing a piece of paper is a physical change because when you rip it,it is still a piece of paper but lets say that u burn a piece of paper its a chemical change couse you cant change it back to wood again
Physical change
To record measurements using a ruler, place the ruler next to the object to be measured. Ensure that the zero mark on the ruler aligns with one end of the object. Read the measurement where the other end of the object falls on the ruler and record it in the appropriate units.
There are two conflicting units at work here. One is the ream as mentioned in the question and one is the quire. "Short" paper measurements insist that there are 24 sheets in a quire and 20 quires in a ream, therefore, "short" paper measurements give 480 sheets to a ream. Writing paper measurements give 25 sheets to a quire and 20 quires, therefore, 500 sheets, to a ream.
A piece of paper has three dimensions. They are the length, width and thickness of the paper. Paper is available in many sizes such as A1, A3, A4 and A5.

A4 paper is exactly half the size of A3, and they both have the same aspect ratio. So A4 --> A3 is an enlargement. Most photocopiers use A4 as standard. You need a larger photocopier to copy onto A3. The photocopier will usually offer A4 --> A3 as an option.
Any good stationary store or on line stationary retailer will supply A3 paper.
