Let us start with the total area of the lawn. Area= width x length, ie, 21 x 20 = 420 sq. ft.   Snow flakes per square foot per minute = 1350  So Snow flakes for 420 sq.feet per minute = 420 x 1350 = 567000.   Snow flakes for 1 hour = 567000 x 60 = 34020000 (60 minutes)  Weight of 34020000 snow flakes = 34020000 x 1.60 = 54432000mg.  To convert it into kilograms, divide this number by 1000000 (1 kilogram = 1000000 milligrams)  Thus 54432000/1000000 = 54.432 kilograms or 54 kilograms and 432 grams.
