Answer 1

Answer:

Space taken by the books = 2880 cm³

Space still empty = 10250 cm³ - 2880 cm³ = 7370 cm³

Step-by-step explanation:

Length of the box = 25 cm

Breadth of the box = 20 cn

Height of the box = 20.5 cm

Volume of a cuboid = Length × Breadth × Height

Therefore,

Volume of

Now,

Length of a book = 16 cm

Breadth of a book = 12 cm

Height of a book = 3 cm

Volume of a cuboid = Length × Breadth × Height

Therefore,

Volume of a book = 16 cm × 12 cm × 3 cm = 576 cm³

Number of books in a set = 5

Number of sets of book = 1

Therefore,

Volume of 5 books = 576 cm × 5 = 2880 cm³

So,

Total space taken by the books = 2880 cm³

Total space left in the box after kepping the books = Volu
