Question

Calculate the volume of a book which is 25cm in length, 12cm in breadth and 2cm 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 length $l$ = $25cm$, breadth $b$ = $12cm$, h = $2cm$
Volume = $l\times b\times h$
= 25$\times$12$\times$2
= $600c{m}^3$
Since $1c{m}^3$ $=({10}^{-2}{)}^3{m}^3$ $={10}^{-6}$$m^3$
Thus the volume of book in $m^3$ = $6\times$${10}^{-4}$$m^3$
