How many 8-inch square floor tiles are required to cover a rectangular floor that measures 15 feet by 18 feet
Answer provided by our tutors
The area of the floor in in^2 is:
A = (12*15)*(12*18) (since 1 ft = 12 in)
The area of one tile is:
A1 = 8*8
A1 = 64 in^2
Let 'x' represent the number of tiles needed, x is integer.
x*A1 >= A
64x >= (12*15)*(12*18)
x >= (12*15)*(12*18)/64
x >= 607.5
This means that 608 tiles are required to cover the floor.
