We have to find the volume of box and one book and then divide it.
Volume of cuboidal box= l x b x h
                                     = 3/2 x 100 cm x 3/4 x 100 cm x 60 cm
                                     = 150 cm x 75 cm x 60 cm
                                     = 675000 cm^3
Volume of book = l x b x h
                          = 20 x 10 x 7.5 
                          = 1500 cm^3

now, 675000 / 1500 = 450
so 450 books can be arranged in the box.
