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.

Dimensions of the cardboard box
Length=3/2m= 3/2×100
=150cm
Breadth=3/4m=3/4×100
=75cm
Height=60cm
Volume of the cardboard box=L×B×H
=150cm×75cm×60cm
=675000cm³
For the books
Length=20cm
Breadth=10cm
Height=7.5cm
Volume of the book=L×B×H
=20cm×10cm×7.5cm
=1500cm³
No. of books that can be arranged in the box=675000cm³÷1500cm³
=450
Therefore, 450 books can be arranged in the cardboard box
