The thickness (width or w) should be converted to cm (0.5mm=0.05cm), then find the Volume of the sheet.
The Volume is r2*pi*w or (20 cm)2(0.05cm) * pi which equals 62.8319 cm3 or 63cm3 when considering the significant digits.
You need to look up the density of aluminum somewhere. If you did you would probably find it to be somewhere around 2.70 grams per cm3
Density(p)=mass(m)/volume(v)
If you multiply v by both sides of the equation you will have m=p*v
mass=(2.70g/cm3)(63cm3)=170.1g or considering the significant digits 170 grams.

Thickness of a sheet of tracing paper?
25 cm
If a aluminum foil is pounded in a sheet of paper what physical propertie has changed?
Density and Luster.
What do you use to measure the thickness of a sheet of paper?
This cannot be done very accurately. However, take enough sheets to make a stack sufficiently high to correspond with the length of the metre rule. Divide the number of sheets by a metre. That will give you the fraction of a metre that one sheet makes.
What is the thickness of a sheet of paper in millimeters?
A ream (500 sheets) of 20 lb office paper is just under 2 inches thick, so one sheet cannot be 0.001 (one-thousandth of an inch). It's closer to 0.004 inches (more like 0.0038). At 25.4 mm per inch, this gives us about 0.09652 mm, or just under one-tenth of a millimeter thick.
How thick is a sheet of notebook paper?
Depends on what paper you're talking about. The average sheet of 20lb copier paper is 0.0038 inches thick; whereas the average sheet of cardstock is 0.0175 inches thick. For a great resource of various thicknesses visit http://iconix.biz/info/paper-weights.htm
What is the way to find the volume of aluminum foil?
Length X Width X Thickness. A sheet of aluminum foil does have a thickness. A typical sheet has a thickness of about 0.02 millimeters. There are, of course, thicker and thinner sheets.
What is the weight of aluminum sheet per square feet?
depends on the thickness of the aluminum (3.25 or 4.25 or 4.5 mm) thickness
What is difference between sheet and plate and foil?
Extremely thin thicknesses are considered foil or leaf. The aluminum foil is a solid sheet of aluminum (or alloy rolled to a thickness of 0.0059inches or less). At a thickness of 0.006inches or more it is referred as sheet and thickness more than 6 mm (0.25 in) is considered as plate.
How do you calculate developed length of sheet metal forming?
ON the cad offset the bend radius from the internal radius of the sheet metal part by 40% of the total sheet thickness,and measure the chord length of the radius. that will be the developed length.
How do you calculate the length of a plain rolled aluminum sheet with width 1219mm and thickness 0.91mm and weight 376kg?
The answer is 12,553 m.
How do you calculate the blank size in sheet metal?
The blank size of sheet metal can be calculated using the bend allowance. This number is based on the metal thickness and the tool radius in the brake.
How do you Calculate the weight of an aluminum coil?
weight of aluminum sheet = lenght (Mtrs) X Width (Mtrs) X Thickness (mm) X density 2.8 g/cm3
What has the author R A Daiuto written?
R. A. Daiuto has written: 'Effect of thickness on fatigue crack propagation in 7475-T731 aluminum alloy sheet' -- subject(s): Aluminum alloys, Fatigue
How do you measure the thickness of thin sheet of paper?
Measure the thickness of multiple sheets (Say, ten or twenty) then divide the answer by the number of sheets to get the thickness of a single sheet.
How can one gauge the thickness of sheet metal?
Sheet metal thickness can be determined by measuring it. Several specialty tools are available to tell how thing the sheet metal is in actual measurement or by guage, a form of measurement that is used for various types of sheet metal thickness.
What is the thickness of a sheet of paper in feet?
Thickness of a sheet of paper would not be measured in feet, but possibly in inches. An average sheet of typing paper is about 1/200 of an inch.
What is aluminum foil?
Aluminum foil is a thin, pliable sheet of aluminum used for cooking, packaging, cosmetics and insulation.
