To determine the number of 30x40 sites (each measuring 30 feet by 40 feet) in 1 acre, you need to convert the measurements to a consistent unit (either feet or square feet). Since 1 acre is equal to 43,560 square feet, let's convert the dimensions of one site to square feet:
30 feet×40 feet=1200 square feet30 feet×40 feet=1200 square feet
Now, divide the total area of 1 acre by the area of one site:
43,560 square feet1200 square feet
1200 square feet/site 43,560 square feet​/site
=36.3 sites
Therefore, approximately 36 to 37 sites measuring 30x40 feet can fit in 1 acre.
