The mass of the snow flakes that accumulates in one hour is 15552 Kg.

What is the mass of the snowflakes?

We know that area is the product of the length and the breadth of the lawn. We have to first obtain the area of the lawn as;

Length = 20.0 feet  

Width =  18.0 feet

Area =  20.0 feet   *  18.0 feet  = 360 square feet

If 1 square feet accumulates 450 new snowflakes every minute

360 square feet accumulates 360 square feet *  450 new snowflakes every minute/ 1 square feet

= 162000 new snowflakes every minute

If 162000 new snowflakes accumulates in one minute

x snow flakes accumulates in 60 minutes

x = 9720000new snowflakes

If 1 snow flake has a mass of 1.60 mg

9720000 new snowflakes has a mass of  9720000 snowflakes *  1.60mg/ 1 snow flake

= 15552000 mg or 15552 Kg
