There are 144 square inches in a square foot.
<u><em>Explanation</em></u>
A common size for floor tiles is 1 square foot in area.
We know that, <u> 1 foot = 12 inches. </u>
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.
