One cubic inch of 6061 aluminum weighs 0.0975 lb
Solid Aluminum is 165 lb per cubic foot. Therefore, 165 divided by 1728 would be .095 lb per cubic inch.
I looked up the density of aluminum, and found 167 pounds per cubic foot.I would have preferred it per cubic inch, as that would have meant less work,but I guess I can convert it.1 cubic foot = 1,728 cubic inches.Density of aluminum = 167/1728 pound per cubic inch.Volume of the sheet = 20 x 20 x 0.25 = 100 cubic inches.Weight = 167 x 100/1,728 = 9.664 pounds
The density of aluminum is approximately 2.7 grams per cubic centimeter (g/cm³). Since there are 16.387 cubic centimeters in a cubic inch, the density of a cubic inch of aluminum is about 43.6 grams. This value can vary slightly depending on the specific alloy and purity of the aluminum.
1 cubic inch of lead has a weight of approx 13.11 pounds weight.
There is no such thing as a 'cubic square inch'. The density of aluminum is 0.0858 pound per cubic inch. (rounded)
The weight of unfilled polycarbonate is 0.0433297 pounds per cubic inch
Teflon weighs approximately .079 LBS per cubic inch.
A cubit is approx 18 inches so the question is concerned with 18 square inches - a measure of area. The weight of 18 square inches of aluminium will depend on its thickness.If the question was about one cubic inch, then the answer is that the weight is approx 3.14 poundals or 0.43 Newtons.
The weight of oxygen per cubic inch is approximately 0.0899 grams.
0.283 pounds per cubic inch
None, since there can be no conversion. A cubic inch is a measure of volume in 3-dimensional space It is not a measure of weight. According to basic principles of dimensional analysis, conversion from one to the other is not valid.If you are not convinced, consider a cubic inch of air. What weight will it have? Next consider a cubic inch of lead. What weight?
