So the correct option is B
The answer is E because 12²
First point to be noted here is, the shelf and the book are 5 inches wide. So it is perfect to hold the book.
The shelf is 56 inches tall and the book is 4 inches thick. To find the number of books Linda can arrange on the shelf, just divide 56 by 4
Number of books Linda can arrange on the shelf = 56 ÷ 4 = 14 books
8 times 12 is 96 and 720 divided by 96 is 7.5. Your answer is 7.5
