A common size for floor tiles is 1 square foot in area.

We know that, 1 foot = 12 inches.

So, 1 square foot = (1 foot × 1 foot)                                                                                 = (12 inches × 12 inches ) = 144 square inches.

So, there are 144 square inches in a square foot.
