How many 4ʹ × 8ʹ sheets of plywood are required to cover a floor that is 9 m by 16 m?

First, we find the area of the floor in square meters.

9 m * 16 m = 144 m^2

Now we convert the square meters to square feet.

144 m^2 * (1 ft)/(0.3048 m) * (1 ft)/(0.3048 ft) = 1550.0031 ft^2

Now we find the area of a 4' by 8' sheet of plywood in square feet.

4 ft * 8 ft = 32 ft^2

Now we divide the area of the floor by the area of a plywood sheet.

(1550.0031 ft^2)/(32 ft^2) = 48.44 sheets.

That means you need to buy 49 sheets.

you take 9m and 16m and convert to feet
3 feet in a meter
27' by 48'

find the area
1296'

find the area of a sheet of plywood
32'

divide the total area by the area of a sheet to get the number you need (40.5) but you cant buy .5 a sheet of that plywood so you need 41
