15 inches X 40 inches = 600 square inches.
Learning how to factor, and/or multiply by basic prime numbers, and/or multiply by 10 will allow you to perform simple figuring such as the following: 15X40=15X4X10=15X2X2X10=30X2X10=60X10=600.
Your figuring may also be thought of without the use of symbols: 15 doubled twice with 1 more zero at the end.
Keep in mind that you must say square as a result of every multiplication problem before the measurement name, because if you don't then you would be giving the measurement of distance instead of a space. Also; be cautious of the fact that 600 square inches is very different from 600 inches squared, and would probably be marked as incorrect if the incorrect answer was written.
