It depends on the density of the plywood. This site shows some plywood densities in kg/m^3. Let's say your plywood is 500 kg/m^3 (which is at the low end of the plywood densities isted on that page). Converting the dimensions of the plywood to meters gives the following:
height: 4 ft = 4 ft * (12 in/ft) * (2.54 cm/in) * (1m/100cm) = 1.22 m
width: 8 ft = 8 ft * (12 in/ft) * (2.54 cm/in) * (1m/100cm) = 2.44 m
thickness: 18 mm * (1m/1000mm) = .018 m
The volume of the plywood is height * weight * thickness = 1.22 * 2.44 * .018 = .0535 m^3.
Weight is density * volume. So, at 500 kg/m^3, the plywood would weigh: 500*.0535 = 26.8 kg. 1 kg is approximately 2.2 pounds, so 26.8 kg is 26.8 kg * (2.2 lb/kg) = 58.9 pounds. If, however for example, your plywood is 700 kg/m^3, it would weigh 40% more, or 82.5 pounds.
About 50 pounds
Well, darling, a 4 x 8 plywood sheet has a total area of 32 square feet. To convert that to square meters, you simply divide by 10.764, giving you approximately 2.97 square meters. So, in short, there are about 2.97 square meters in a 4 x 8 plywood sheet.
80 sheets
Four sheets of 4' by 8' plywood will be required to cover a shed roof measuring 10' by 12'. Three of the sheets can be used as is, but one of the sheets will need to be cut to fit.
13 ft by 23 ft = 299 ft2 and one standard sheet of plywood is 4 ft by ft = 32 ft2. 299 / 32 = 9.34 sheets, so you will need to purchase 10 sheets of plywood.
2400 per sheet 8*4=32 sq feet.
The weight of plywood can vary depending on the thickness and type of wood used. On average, a 4-foot by 8-foot sheet of 3/4-inch-thick plywood weighs around 60-70 pounds.

The weight of treated plywood can vary depending on the type of treatment and thickness of the plywood. On average, a 4'x8' sheet of 3/4" treated plywood can weigh between 60-70 pounds. It's always best to check with the manufacturer for specific weight information.
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.
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.
Luan plywood typically comes in thicknesses ranging from 1/8 inch to 1/4 inch.
The weight of lauan plywood can vary depending on its thickness and size. On average, a 4'x8' sheet of 1/4" lauan plywood weighs around 22-26 pounds, while a 4'x8' sheet of 3/4" lauan plywood can weigh approximately 60-70 pounds.

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 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.
