Respuesta :
If a stack of books is 5 feet high, and the average book is 3 inches thick (high), how many books are in a stack?
Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20.
Your answer is: 20 books are in a stack.
There'll be 20 books which can be found in the stack.
Note that 1 foot = 12 inches
Therefore, 5 feet will be changed to inches and this will be:
= 5 × 12 = 60 inches.
Therefore, the number of books will be:
= 60 inches / 3 inches.
= 20
Therefore, there'll be 20 books.
