Hi there,
Convert feet into inches.
10 feet = 120 inches
12 feet = 144 inches
Area of floor = 120 inches x 144 inches
Area of floor = 17280 inches^2
Area of tile = 10 inches x 10 inches
Area of tile = 100 inches^2
Divide area of of tile into the area
of the floor:-
17280/100
= 172.8 tiles or 173 tiles.
Hope this helps :-)
