Answer:8 books

Step-by-step explanation:thickness of each book = 21 cm

1m 80 cm = 180 cm

no of books in this space = 180/21 = 8 books

Step-by-step explanation:Total number of books adjusted = Length of shelf ÷ Thickness of 1 book

= 1 m 80 cm ÷ 21 cm

= 180 cm ÷ 21 cm

= 8.571

Books can’t be in fraction or decimal form…..

So the number of books that can be adjusted in the shelf is 8.
