If your front lawn is 25.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates new snowflakes every minute, how much snow (in kilograms) accumulates on your lawn per hour? assume an average snow flake has a mass of 2.00mg

The lawn accumulates a new layer of snowflakes every minutes.

Lawn size = 500 sq ft
Minutes in an hour = 60 minutes

Layers accumulated = 60
Let there be 1000 snowflakes in a layer
Snowflakes = 500 x 60 x 1000
= 3 x 10⁹ snowflakes
Mass = 3 x 10⁷ x 2 x 10⁻⁶ kg
Mass = 60 kg of snow
