Question

A book is 14 cm long, 8 cm wide and 2 cm high. What is the volume of 2 such books piled one on top of other?

• A. 224 cubic cm
• B. 244 cubic cm
• C. 428 cubic cm
• D. 448 cubic cm

Answer 1

The correct option is D 448 cubic cm

Volume of 1 book = $l\times b\times h$


$\therefore \text{Volume}=14\times 8\times 2=224\text{cubic cm}$

When the 2 books of same measure are piled up on one another their length and width will remain same but height increases.

$\therefore \text{Volume}=14\times 8\times 4=448\text{cubic cm}$
