Question

A book is 24 cm long , 14 cm wide and 2 cm high. What is the volume of 12 such books piled

on top of the other?​

Answer 1

Volume of a cuboid = lbh

where, l is the length, b is the breadth/width, and h is the height.

Given, length is 24 cm, breadth/width is 14 cm, and height is 2 cm

According to the formula,

Volume of the book

ㅤﾠﾠﾠﾠﾠﾠﾠㅤㅤㅤ= lbh

ㅤﾠﾠﾠﾠﾠﾠﾠㅤㅤㅤ= ( 24 × 14 × 2 ) cubic.cm

ㅤﾠﾠﾠﾠﾠﾠﾠㅤㅤㅤ= 672 cubic.cm

The volume of 12 such books is 12 times 672 which is 8064 cubic.cm .

Answer 2

$\sf{\huge{\underline{\green{Given :-}}}}$

• A book is 24 cm long , 14 cm wide and 2 cm high.

$\sf{\huge{\underline{\green{To\:Find :-}}}}$

• The volume of 12 such books piled on top of the other.

$\sf{\huge{\underline{\green{Answer :-}}}}$

We have the dimensions of book ,

• Length = 24 cm

• Width = 14 cm

• Height = 2 cm

The books are rectangular in shape. So, it's 3D figure is cuboid.

The volume of 12 books = 12 × Volume of 1 Book

Volume of 1 Book = Volume of cuboid

We know, that the Volume of cuboid = L × B × H

➝ Volume of 1 Book = L × B × H

➝ 24 × 14 × 2

➝ 336 × 2

➝ 672 cm³

The volume of 12 books = 12 × Volume of 1 Book

➝ 12 × 672

➝ 8064 cm³

The volume of 12 such books piled on top of the other is 8064 cm³ .
