To find the number of posts needed for the nine rows, we need to calculate the total number of posts placed in a single row and then multiply it by nine.
In a single row, the posts are placed at 1.2 m intervals. So, the distance covered by a single post and the gap between two posts is 1.2 m.
Therefore, the number of posts needed in a single row can be calculated by dividing the length of the row by the distance covered by a single post and the gap between two posts:
Number of posts in a single row = length of the row / (1.2 m + 1.2 m)
Now, the posts in the new nine rows are placed at 1.3 m intervals. So, the distance covered by a single post and the gap between two posts is 1.3 m.
Therefore, the number of posts needed in a single row for the new interval can be calculated by dividing the length of the row by the distance covered by a single post and the gap between two posts:
Number of posts in a single row for the new interval = length of the row / (1.3 m + 1.3 m)
Finally, to find the total number of posts needed for the nine rows, we multiply the number of posts needed in a single row for the new interval by nine:
Total number of posts needed for the nine rows = Number of posts in a single row for the new interval * 9
Note: Since the length of the row is not provided, it is not possible to calculate the exact number of posts needed.
a farm has an old pod supported by 650 posts that are placed at 1.2 m intervals how many posts needed to be placed for the nine rows in which the posts will be placed at 1.3 m intervals
