Answer:
9 bookcases.
Step-by-step explanation:
Total number of books = 943
Total number of books placed in one shelf = 22
Total number of shelves in one bookcase = 5
Total number of books displayed in one bookcase = [tex]No.\ of\ shelves\ in\ 1\ bookcase\times\ No.\ of\ books\ in\ each\ shelf[/tex]
Total number of books displayed in one bookcase= [tex]5\times 22=110[/tex]
Total number of bookcase required = [tex]\frac{total\ no.\ of\ books}{Number\ of\ books\ displayed\ in\ 1\ bookcase}[/tex]
Total number of bookcase required = [tex]\frac{943}{110} =8\frac{63}{110}[/tex]
So, 880 books can be displayed in 8 bookcases. and for the remaining 63 books we also require one more bookcase. Therefore, the total number of bookcases needed are 9.
