Given is a stack of books, each 9 by 12 by 1 inch. What should be volume of the books?

1 book = 108 inches^3

Step-by-step explanation:

I take that each book is 9 by 12 by 1

To find the volume you must times length, width, and height together

9*12*1 = 9*12 = 90 + 18 = 108 inches^3

To find the total volume of the stack take this number and multiply by number of books
