A rule of thumb is 25lbs per 1/4" of thickness, so for 3/4" would be around 75lbs.
that depends on the type of plywood 3/4" ranges from about 20.00 to about 50.00 a sheet (cheap flooring to higher end finish plywood and marine grade pressure treated) in my area. . .check around.
The thickest plywood sheet available for purchase is typically 1 1/8 inches thick.
Trick question! A single sheet of OSB weighs about 1.5 lbs per sf or 47 lbs, assuing you are asking about 7/16" thick, not 716. One sheet of plywood weighs a bit more. There is no such thing as OSB plywood! That is like asking how much does a motorcycle car cost?
20-25 pounds per sheet, per 1/4" of thickness. In other words, about 25 pounds for a sheet of 1/4, about 50 pounds for a sheet of 1/2.
when asking this question you first need to take into account that plywood comes in different thicknesses therefore weight per particualr thickness of sheet plywood will vary-- in my opinion/ without fact and research / a sheet of 1/2 inch plywood may way about 16 lbs. while a 3/4 inch plywood sheet may way 70 lbs.
The birch veneer is actually accounts for a small portion of the plywood's density. The core layers are more important. The Purebond plywood that I see at my local home despot is probably from Columbia Forest Products. According to their website, my plywood on the east coast is composed of a combination of aspen and fir layers. Birch has a density of 670 kg/m3, Aspen 420 kg/m3, and Fir 530 kg/m3. If you don't know what kg/m3 means, I did an estimate on the math. Guessing that the board is 2/3 Fir and 1/3 Aspen, and neglecting the millimeter of birch on top, the weighted average density is 494 kg/m3 or about 31 lb/ft3. If you still don't know what lb/ft3 means, basically a 4 by 8 sheet of plywood, 3/4" thick, should weight about 59 pounds. A half inch thick sheet, should weight about 39 pounds; and a quarter inch thick sheet should weigh in at around 18 pounds.
No, not safe; if supported on each end it is likely to break
I need the thickness dimension of 12 ply plywood for floor.
The subfloor plywood typically used in construction projects is around 3/4 inch thick.
It depends on the type of armor you need: Body Armor: A thick jacket/coat, with many pockets to fill with flat, lightweight objects (such as plywood) Field Armor: (for cover): Large plywood sheets standing uprights with a flat base bolted to the sheet.
A US quarter is 1.75 mm thick. Canadian quarters are 1.58 mm thick.
it depends if it is a real mirror and how thick/ tall it is :D
