Question

In a library 126 books required a shelf length of 3.78 how how many books occupy a shelf length 4.6 metre

Answer 1

Answer:

The number of books is 153

Step-by-step explanation:

Let us assume that the books are kept against each other, without any space in between.

It is given that 126 books need a shelf length of 3.78 metre

Now, 1m = 100cm

Thus, 126 books need 378cm

=> 1 book needs 378/126 = 3cm

Therefore, a shelf length of 4.6m or 460 cm will cover 460/3 books

No. of books = 460/3 = 153.333

As the number of books has to be a natural number, the maximum number of books that a shelf length of 4.6m can fit is 153.
