Question

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

Answer 1

[m(100cm/m)(in/2.54cm)(ft/12)]^2=(25/7.62)^2 ft^2

(9*16)m^2(25ft^2/7.62m^2)(sheets/(4*8)ft^2)≈48.44 sheets

In reality you must buy complete sheets, or integer values, so you would need 49 sheets to cover the floor :P

Answer 2

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.
