Answer 1

Answer:

$\tt 1 \: book$

Step-by-step explanation:

$\boxed{\rm Volume_{Cuboid} = l×b×h}$

Volume of each book,

$\tt 20×12×6=1440 \: {cm}^{2}$

$\boxed{\rm Volume_{Cube}=(side)^2}$

Volume of cubical box,

$\tt (120)^2 =1440 \: cm^2$

Books can be filled in the cubical box,

$\tt \dfrac{1440}{1440}=1 \: book$
