It is: 660 ft = 1/8 of a mile
660 yards = 0.375 miles
it's exactly 55 ft.

1 acre = 43,560 sq ft(660 x 660) = 435,600A square with 660-ft sides encloses 10 acres.
660 *15 = 9900 miles
Remember the Imperial table for length. 3 ft = 1 yard 22 yds = 1 chain ( 22 x 3 = 66 ft ) 10 chains = 1 furlong ( 66 ft X 10 = 660 ft) 8 furlong = 1 mile = ( 660 X 8 = 5280 ft in 1 mile) Hence in 5 miles there are 5 x 5280 = 26400 ft).
660 x 660 = 435,600. There are 43,560 sq ft per acre. So, we would divide 435,6000 by 43,560 which is exactly 10. So, the answer is 10 acres.
660 miles
660 feet = 1/8 of a mile (0.125 miles).
There are 1.609344 kilometres in one mile. Therefore, 660 miles is equal to 660 x 1.609344 = 1062.16704 kilometres.
3 feet = 1 yard; 660/3 = 220.
