The inside measurements of a cardboard box are 3/2m by 3/4m by 60cm. how many books 20 cm by 10 cm by 7.5 cm each can be arranged in the box.

Given,


Dimensions of box


Length (L) = 1.5m = 150cm


Breadth (B) = 0.75m = 75cm


Height (H) = 60cm


Dimensions of book


Length (l) = 20 cm


Breadth (b) = 10 cm


Height (h) = 7.5 cm


The volume of the box = L × B × H


= 150 × 75 × 60


= 675,000 cm3


Volume of book = l × b × h


= 20 × 10 × 7.5


= 1500 cm3
