I am in the very early part of a plan to build a hardwood base for a glass top table. My daughter has gotten a very large piece of 3/4″ soda glass which is 24.75″ on each side of an octagon(20.5ft square surface) I have not been able to determine its weight. I know it’s heavy. I would love to have a formula and constants to determine this and would be wide open to advice from someone who has experience in such a project, ie which species and any design ideas. I am modestly skilled but humble.
Thanks, Mike C

According to a document on the Glass Association of North America (GANA) site, the estimate would be 9.8 pounds per square foot for 3/4" thick glass. (http://www.glasswebsite.com/)
Here's a link for calculating the area of the octagon:

Mike,
The glass weighs just a shade over 195 lbs.
Density of soda glass = 2.44 g/cm3 = .088151 lb/in3
Area = 20.5 ft2
Thickness = 3/4 in
144 in2 / 1 ft2 x 20.5 ft2 x 0.75 in x .088151 lb/in3 = 195.16 lb
Of course you'll want to check my arithmetic. I always say, there's only two things that confuse me, mathematics and electricity...

Thank you, Fred. I guessed in your very helpful area but am also aware that guesses in physics often are worthles.Mike
set it on your bathroom scale....
