The easiest way to determine an honest weight of a 4' x 8' sheet of plywood? 20-25 pounds per 1/4" of thickness. 3 pounds per square foot per inch of thickness according to APA Plywood Design Specification.

It depends on how big a sheet of plywood you are talking about.
The answer will depend on the size of the plywood sheet!
3,600 square inches.
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.
About 50 pounds
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.
1/3 square foot.

It depends what the "ply" value is ... the number of layers glued together. For instance, 1/2" plywood is going to be lighter then 3/4" plywood. A common rule of thumb is a 4x8 foot sheet of 1/4" fir plywood weighs 25 pounds. There are 32 square feet in a sheet, so a square foot of 1/4" fir plywood weighs about 0.78 pounds. Since 1/2" is twice as thick as 1/4", 1/2" fir plywood weighs twice as much, or 1.56 lbs, and 3/4" three times as much, or about 2.34 lbs. Fir plywood is common, but other species are available. Weight varies considerably between species of wood, so be aware the weight of plywood of different species can be different.

Yes, one can you put A 4 x 8 sheet of plywood in a Ford Flex.
A full sized mattress is 54" x 75". If you want an edge around the mattress (for example, if you are making a platform style bed) then figure out the edge you want and calculate accordingly. I always use a piece cut exactly to the mattress measurements, and that works fine for me.
