Question

A cubical box of length 120 cm has to be filled with cuboidal books of dimension 20 cm X 12 cm x 6 cm. How many such books can be filled in the cubical box ?​

Answer 1

Answer:

the number of books that can filled = 1200

Step-by-step explanation:

Given length of cubical box = 120 cm

the volume of the cubical box = $s^{3}$  ( s is side or length of the box )

                                                   = $120^{3}$ =  1728000 $cm^{3}$

the box has to be filled with  cuboid shaped books

   the dimensions of books =   20 cm × 12 cm× 6 cm

   volume of the each book (v) =   $lbh$

                                                    =  20 ×12 ×6

                                                    = 1440 $cm^{3}$

 number of books that can be filled the cubical box  

                                                    =  $\frac{volume cubical box }{volume of the book}$ =    $\frac{1728000}{1440}$ = 1200 books
