Question

The length, breadth and height of a glass slab are respectively $50cm$, $20cm$ and $25cm$. Find the order of magnitude of volume of slab in Sl unit.

• A. ${10}^{-2}{m}^3$
• B. ${10}^{-4}{m}^3$
• C. ${10}^{-3}{m}^3$
• D. ${10}^{-3}c{m}^3$

Answer 1

The correct option is A ${10}^{-2}{m}^3$

$L=0.5m,b=0.2m,h=0.25m$

Volume $=$ length $\times$ breadth $\times$ height

Volume $=l\times b\times h=0.025m^3=2.5\times {10}^{-2}{m}^3$

So, the order of magnitude is ${10}^{-2}{m}^3$.
