how much snowfall will cover 10 square miles of land if you estimate?
Sally lives on a farm that covrs ten square miles. On Christmas Day it snows steadily from morning till night. Sall wants to estimate how many snowflakes fell on her farm on Christmas Day. How might Sally go about making her estimate? Show your work.
Count the snow flakes covering 1 square foot.
1 mi^2 * (5280^2 ft^2 / 1 mi^2) = 27878400 ft^2
1 square mile = 27878400 square feet
10 square miles = 278784000 square feet
Multiply the number of snow flakes she counted from her 1 square foot by 278784000 to get an estimate of the number of snow flakes covering 10 square miles.
