@Randy Dandy,

No Algebra. Arithmetic
You have the square footage and the number of square inches.
How many stitches per square inch?
Multiply that number by the square inches.
Divide the result by the number of stitches per minute.
See if that works for the number of minutes.

@neologist,

neologist,

24 stitches per square inch.

24 * 3456 = 82944 stitches.

82944 / 8 = 10368 minutes

10368 / 60 minutes per hour = 172 .8 hours / 24 hours per day = 7.2 days
