If the piece of sheet metal is a square, then 1600 cm2.
69 cubic centimeters squared
No,You are confusing volume measurements with area measurements.You could ask could 3- cubic centimeters of a liquid disperse to cover an area of 225 square centimeters. This then is a science question that deals with the properties of the liquid and the surface in question.
A sharp metal piece is typically called a "metal shard" or a "metal splinter."
A 'metal filing ' is a tiny piece of metal that is rubbed off from a large piece by a file.
a ruler
The conversion factor is 0.155: 20sq cm x 0.155 = 3.1 inches squared
The speed at which a given piece of metal rusts depends upon the type of metal it is - pure iron rusts much faster than most iron alloys - as well as exposure to water and other rust catalysts. Furthermore, the dimensions that you give, 3 by 0.5 by 3, don't mean anything unless you give units, such as, 3 inches, or 3 centimeters, or 3 feet, etc. The dimensionless number does not describe the size of a piece of metal.
A standard piece of paper, such as A4 size, measures 21 centimeters in width and 29.7 centimeters in height. In the U.S., a standard letter-sized paper measures 21.6 centimeters by 27.9 centimeters. The dimensions can vary for different types of paper, but these are the most commonly used sizes.
A metal burr is a small, thin edge of metal that is created when a piece of metal is machined. For example: when a chef's knife is sharpened, a thin piece of metal remains on the edge of the knife.
its a piece of curved metal with another piece of metal going through it at the top
Volume cannot be measured in centimetres. Without the volume in appropriate units, the question makes no sense and so cannot be answered.
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
