Final answer:
To calculate the ad size in agate lines for a 5 columns by 10 inches ad, you convert the measurements to lines using the standard of 14 lines per inch. A 10-inch depth is 140 lines deep, and assuming a column width of 2 inches, a 5-column width is 140 lines wide. Thus, the ad is 19600 agate lines in size.
Step-by-step explanation:
If an advertiser wants to run an ad that is 5 columns by 10 inches deep, the size of the ad in agate lines can be calculated knowing that an agate line is approximately 1/14th of an inch. First, we need to convert the measurements of the ad from columns and inches to lines.
To calculate the total number of agate lines, we multiply the depth of the ad in inches by the number of lines per inch. Since an agate line is 1/14th of an inch, there are 14 lines per inch. So, a 10-inch deep ad would be:
10 inches × 14 lines per inch = 140 lines deep.
The ad's width in columns needs to be converted into lines. Typically, newspaper columns are about 1.5 to 2 inches wide, but this varies depending on the publication. Assuming a standard width of 2 inches per column, a 5-column wide ad would be:
5 columns × 2 inches per column × 14 lines per inch = 140 lines wide.
Therefore, the total size of the ad in agate lines would be the width in lines times the depth in lines:
140 lines wide × 140 lines deep = 19600 agate lines.
