Question

Calculate the volume of a book which is 25 cm in length, 12 cm in breadth and 2 cm in height.

• A. $6\times {10}^{-4}{m}^3$
• B. $600m^3$
• C. $6\times {10}^{-6}{m}^3$
• D. $12\times {10}^{-4}{m}^3$

Answer 1

The correct option is A $6\times {10}^{-4}{m}^3$

Given:
Length of book, $l=25cm$
Breadth of book, $b=12cm$
Height of book, $h=2cm$

Volume of the book is giveb by:
$V=lbh$
$V=25\times 12\times 2c{m}^3$
$V=600{cm}^3$

Using conversion of prefixes,
$1c{m}^3={10}^{-6}{m}^3$

Thus, the volume of book is:
$V=600\times {10}^{-6}{m}^3$
$V=6\times {10}^{-4}{m}^3$
