You find 30 seashells in a 2ft by 2ft section of a beach how many seashells do you find in a 1/2 mile wide and 3 miles Long Beach

Question

This is estimating large numbers for quatative reasoning

Answer 1

Compare beach areas: 2×2=4sq ft.

1 mile=5280 ft, so ½mile=2640ft.

3 miles=15840ft. Area of Long Beach=15840×2640.

Divide by 4 to find out how much Long Beach is bigger than the small beach area=15840×2640÷4=10,454,400.

So we would expect this number times 30 shells=313,632,000 shells approximately.

For quantitative estimates call this 300 million shells.
