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.
A three quarter inch plywood trailer floor can typically support a distributed load of about 50-60 pounds per square foot. However, the weight capacity may vary depending on the quality of the plywood used and the design of the trailer.
Assuming that the piece of plywood is approximately rectangular, simply cut off any two corners. It will then be a hexagon.
245 lbs
A rule of thumb is 25lbs per 1/4" of thickness, so for 3/4" would be around 75lbs.
1/4 = 2/8 so the 3/8 is thicker.
The United States one quarter coin has a thickness of 1.75 millimetres, or, rounded to three significant figures, 0.0689 inches.
Yes it can. That seems a very satisfactory way to do it.
There are two primary reasons for the use of veneer in a woodworking project: strength and price. In the matter of strength, most veneered wood is a form of plywood. Plywood comes in a variety of strands (plys), from three-ply to laminated products of 20, 50, or 100+. The greater the ply, the stronger the product due to the cross-biased construction. As far as price, the cost of a piece of plywood with a rare wood face such as mahogany or rosewood is vastly lower than a piece of solid lumber. The face being 1/64th to 1/16th inch thick will show the same beautiful grain as a solid piece for a fraction of the cost, and the workability of plywood is negligibly the same as a solid piece of lumber.
You did not mention if the three-quarter inch stuff was T&G (tounge and grove), that might make a little difference. I am not an expert in this area but have some personal experiences to share. I was allways told from old school you should have two layers of half inch material one layer turned ninety degrees from the other to give a solid one inch floor. Then you could use the one quarter backerboard and end up with a good tile floor. Then the new school came along and told me i could use one quarter over the T&G three quarter. They said the three quarter T&G was equal to the old style one inch. I tried it with the three quarter and i have several grout cracks and two broken tiles. I was using one quarter quarry tiles six by six. Have now fixed yet but in another room i used three quarter T&G plus another one half inch plywood then one half inch backerboard and same tiles no cracks.
Three quarters is bigger
12 x 3 / 4 = 9 The stack is 9 inches high.
It's a rubber seal about a quarter inch thick, and about three inches across... usually brown.
