16 x 12 = 192 sq ft one 4 by 8 plywood sheet = 8 x 4 = 32 sq ft 192/32 = 6 sheets
Yes. Multiply length by width - the result is the area in square feet.
4' X 8' = 32 sq. ft.
140
-- Plywood normally comes in 4-ft x 8-ft sheets = 32 square feet.-- The area you have to cover is 10-ft x 12-ft = 120 square feet.You need 120/32 = 33/4 sheets worth of material, but you'll have tofigure out for yourself how to cut it.
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.
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.
8, and you'll have a plywood board that is 4 by 4 leftover.
12 ft * 12 ft = 4 yd * 4 yd = 16 sq yards
You need 63 sheets at 8 by 4 sheets. There will be some waste so buy a few more.
1 plus 4 sq ft
Area = Length × width 12 × 4 = 48 ft2
