    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.
