It is quite simple. You must calculate this formula first:
I=klm(x)+Y(klm)
Then you must do the prime factorization of "I" and times it by "klm" After you have completed this, times your answer by "Y" and you will have how many square per inches.
(16" x 16") = 256 square inches(256 square inches) / (144 square inches per square foot) = 1 and 7/9 square feet

1 square kilometer = 1 550 003 100 square inch
(2 square yards) x (1,296 square inches per square yard) = 2,592 square inches
18 cases Math: each tile is 5in X 5in = 25 square inches per tile 25 square inches per tile X 75 tiles per box = 1875 square inches per case 1875 square inches per case / 144 square inches per square foot = 13 square feet per case 225 square feet in the room / 13 square feet per case = 17.3 cases or 18 full cases.
320 square inches
There are 36 inches in a yard (12 inches per foot times 3 feet per yard), so a square yard is 36 times 36 or 1,296 square inches. So 1,600 square inches is greater.
