Answer:
To find the surface area of a pyramid, start by multiplying the perimeter of the pyramid by its slant height. Then, divide that number by 2. Finally, add the number you get to the area of the pyramid's base to find the surface area.
Step-by-step explanation:
[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
