If your front lawn is 16.016.0 feet wide and 20.020.0 feet long, and each square foot of lawn accumulates 13501350 new snowflake

asambeis [7]

Answer:

The mass of snow accumulated in the lawn in 1 hour equals 57.024 kilograms

Explanation:

Given

Width of lawn = 16 feet

Length of lawn = 20 feet

Thus total area of lawn equals $16\times 20=320sq.feet$ \

Now it is given that 1 square foot accumulates 1350 new snowflakes each minute thus number of snowflakes accumulated by 320 square feet in 1 minute equals

$320\times 1350=432000$

Now it is given that average mass of each snowflake is $2.20mg=2.20\times 10^{-3}g=2.20\times 10^{-6}kg$

Hence the mass accumulated per minute equals $432000\times 2.20\times 10^{-6}=0.9504kg$

Now since there are 60 minutes in 1 hour thus the mass accumulated in 1 hour equals $0.9504kg\times 60=57.024kg$
