Question

Calculate the volume of a book which is 25 cm in length, 12 cm in breadth and 2 cm in height in $m^3$.

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

Answer 1

The correct option is A

$6\times {10}^{-4}{m}^3$

Given l=25 cm, b=12 cm, h=2 cm
Volume =$l\times b\times h$
= $25\times 12\times 2$
= $600c{m}^3$
Since $1c{m}^3=1/1000000m={10}^{-6}{m}^3$
Thus the volume of book in $m^3=6\times {10}^{-4}{m}^3$
