Answer 1

Explanation:

Measurements of cardboard box-

length(L)=(3/2)m=150cm

breadth(B)=(3/4)m=75cm

height(H)=60cm

Measurement of book-

length(l)=20cm

breadth(b)=10cm

height(h)=7.5cm

Let no. of books in cardboard box = n

If we observe clearly,no. of books that can be arranged in the cardboard box=

Volume of cardboard box= n × no. of books

=>L×B×H=n×lxbxh

=>n=(L×B×H)/(l×b×h)

=>n=(150×75×60)/(20×10×7.5)

=>n=675000/1500

=>n=450

Therefore, 450 books can be arranged in the cardboard box.
