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 subfloor plywood typically used in construction projects is around 3/4 inch thick.
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.
For optimal support and durability, the plywood under a mattress should be at least 3/4 inch thick.
For a subfloor, typically 3/4 inch thick plywood is recommended for stability and durability.

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.
For flooring, it is recommended to use plywood that is at least 3/4 inch thick to provide sufficient strength and durability.
The best plywood to use for an attic floor is typically 3/4 inch thick, tongue-and-groove plywood. This type of plywood is strong and durable, providing a sturdy surface for walking and storing items in the attic.
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.
For a mobile home floor, typically 3/4 inch thick plywood is recommended for optimal strength and durability.
The best plywood to use for attic floor storage is typically 3/4 inch thick, tongue and groove plywood. This type of plywood is strong and durable, providing a stable surface for storing items in the attic.
