In the first row there are language books,in second row science books ,in third row math books and in the remaining rows story books. Find the number of story books in the section

Answer 1

Answer:

There are 15,360 storybooks in that section

Step-by-step explanation:

So first you have to find out how many books there are total. That means you multiply the amount of columns by the about of books in each column.                 16 times 192 equals 3072. There are 3072 in each row of 16 columns. Now you would count the amount of rows that don't have story books. That equals 3 rows. 8 rows minus 3 non-storybook rows equals 5 storybook rows. This means you multiply 5 rows by the 3072 books in each row. 5 times 3072 equals 15360. This means there are 15,360 story books in that section.
