    41

    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

    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.
