Thanks for asking scootrnerd. If that's one inch, his weight is WAY off. So be careful of his other answers.
One inch glass weighs 13.5lbs/sqft
38/12 = 3.17ft
6 x 3.17 x 2 = 38sqft (front and back)
3 x 3.17 x 2 = 19sqft (ends)
6 x 3 = 18sqft (bottom)
38+19+18=75sqft
75 x 13.5 = 1012lbs.
That doesn't include the frame or any bracing.
That would take strong guys shoulder to shoulder to budge.
