Question

A book is 24cm long,14cm wide and 2 cm high. what is the volume of such 2 books piled one on top of the other

Answer 1

Answer :-

• The volume of such 2 books piled one on top of the other is 1344cm³.

Step-by-step explanation :

To Find :-

• The volume of two books piled one on the top of the other.

Solution :-

Given that,

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

Therefore,

• Length = 24cm
• Breadth = 14cm
• Height = 2cm

The volume of the book is, As we know that,

Volume of cuboid = lbh

Where,

• l = Length
• b = Breadth
• h = Height

=> Volume = Length × Breadth × Height

=> Volume = 24cm × 14cm × 2cm

=> Volume = ( 24 × 14 × 2 ) cm³

=> Volume = ( 24 × 28 ) cm³

=> Volume = 672cm³

• The volume of the book is 672cm³.

According the question,

The volume of such 2 books piled one on top of the other is,

=> 672 × 2

=> 1344

• The volume of such 2 books piled one on top of the other is 1344cm³.

Answer 2

Given:

A book with

• Length = 24 cm
• Width = 14 cm
• Height = 2 cm

What To Find:

We have to find the volume of two books piled one on the top of another book.

How To Find:

To find the volume of two books, we will

• First, find the volume of one book.
• Then, find the volume of two books.

Formula:

Volume of one book = Length × Width × Height

Volume of two books = 2 × Length × Width × Height

Solution:

• Finding the volume of one book

Using the formula,

⇒ Volume = Length × Width × Height

Substitute the values,

⇒ Volume = 24 cm × 14 cm × 2 cm

Multiply the sides,

⇒ Volume = 672 cm²

• Finding the volume of two books

Using the formula,

⇒ Volume = 2 × Length × Width × Height

Substitute the values,

⇒ Volume = 2 × 672 cm²

Multiply the sides,

⇒ Volume = 1344 cm³

∴ Thus, the volume of two books piled together is 1344 cm³.
