How many square inches are in 60 square feet

jasenka [17]

<h2>Answer</h2>

8640 square inches

<h2>Explanation</h2>

To solve this, we are going to take advantage of the fact that 1 square foot is equal to 144 square inches so we can create a suitable conversion fraction.

Since we want to convert from square feet from inches, the denominator of our conversion fraction will be square feet so we can cancel those out and get the result in square inches:

$60square.feet*\frac{1144square.inches}{1square.fett} =60*144square.inches=8640square.inches$

There are 8640 square inches in 60 square feet
