Planning & EstimatingCâu 539 / 700
A straight fence run is 240 ft long with posts spaced 8 ft on center. Counting both end posts, what is the MINIMUM number of posts required?
a.30 posts
b.32 posts
c.31 posts
d.240 posts
Giải thích
Number of spaces (sections) = 240 / 8 = 30. For a straight run, posts = sections + 1 = 31, because both ends need a post. Option a counts spaces, not posts. Option b adds one too many. Option d confuses feet with posts. For a straight line, remember to add one post for the final end.
