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
I see no reason why the weight should change if you crumple it.
no aluminium sheets absorb heat
Have you heard of Archimedes. Well he stated that the weight of water displaced by an object is equal to the weight of the object. From here we conclude that object being more denser than water sinks those being less dense than water floats. An Aluminum cube has a much higher density than that of water and the sheet is less dense than water. Thus the former floats while the latter sinks. Now you also might have noticed that an iron nail sinks while an iron ship floats. I hope now you can answer this question!!
18.88lbs/sheet for an 1/8" thick sheet
how we can calculate the formula of Gi sheet
The density of aluminum is 2.7 g/cm3, so in doing the math, assuming the sheet is 4' x 8' x 1/4", the volume is 1152 cubic inches, or 18,878 cubic centimeters. The weight would be 51 kg, or 112 pounds.

depends on the thickness of the aluminum (3.25 or 4.25 or 4.5 mm) thickness
One can easily calculate the weight of a 1 cm thick aluminum sheet in several ways. First, one can use a scientific scale for a very accurate measurement. Also, one can calculate the volume by submerging the sheet in water, and calculate the weight using the density of aluminum, which is 2.70 grams per cubic cm.
weight of aluminum sheet = lenght (Mtrs) X Width (Mtrs) X Thickness (mm) X density 2.8 g/cm3
84.8 lbs.
The answer is 12,553 m.
I see no reason why the weight should change if you crumple it.
Aluminum foil is a thin, pliable sheet of aluminum used for cooking, packaging, cosmetics and insulation.
specific weight of the sheet * area *thickness = weight of the sheet
The density of aluminum is 2.7 g/cm3, so in doing the math, assuming the sheet is 42' x 8' x 1/4", the volume is 12096 cubic inches, or 198,217.93 cubic centimeters. The weight would be 535.188411 kg, or 1177.4 pounds.
I don't have a numeric answer for you, however, I do know that sheet aluminum has better thermal conductivity than cast. It has to do with the way that cast aluminum cools.
