Max builds rail fences.for one style of fence each section uses 3 vertical fence posts and 6 horizontal rails.how many rails does he need for a fence that has 27 posts
To find out how many posts are needed to build a fence with 10 sections, we need to understand the arrangement of the posts. Each fence section has a post at each end, so the number of posts required is equal to the number of sections plus one.
In this case, we have 10 sections, so we add one to get the total number of posts needed: 10 + 1 = 11.
Therefore, the correct answer is 11 posts.
