The amount of fence needed to surround 2 acres depends on the perimeter, not the area.
32 posts
56 posts are needed for the fence
To calculate the number of posts you would need to no the shape of the 20 acres. If we assume the land is square we can calculate the length of one side of the 20 acres as follows: 1 Acres equals 43,560 square feet 20 acres equals 20 X 43,560 = 871200 square feet. We can find the length of one side by taking the square root of 871200 = 933.4 feet. Divide the length of one side by the spacing of the posts and multiply by 4 to get the total number of posts. so for 12 feet spacing of posts 933.4 /12 X 4 = 312 posts.
5 vertical posts are needed. I---I---I---I---I

Well, first you need to know the length of barbed wire in a roll. Then you need to know the perimeter of the fence (in feet or metres) you are going to build around that 180 acres. Then, calculate it this way: (length of barbed wire in one roll) x (perimeter of fence of 180 acres) = (total length of wire needed for "n" ft. (or m) of fence perimeter of one strand) (total length of wire needed for "n" ft.(or m) fence perimeter of one strand) x 5 = (Grand total length of wire needed to fence 180 acres) (Grand total length of wire needed to fence 180 acres) / (length of barbed wire in one roll) = (# of rolls needed for a five-strand barbed wire fence for 180 acres)
Any measure greater than or equal to 1181 feet - up to infinitely many feet.
80 acres is 880 x 440 feet. Depends on how many cattle and how rough they are on your post settings. Most people around here in Oklahoma put their t-posts roughly 16' apart. This will take 164 posts. A roll of barbed wire will usually run a quarter of a mile of fence. So on a typical 5 wire fence it will take 30 rolls of barbed wire.
6600 the correct answer is actually 6601 because you need one more post to close the fence.
