An iron block has a length of $20cm$, breadth of $10cm$ and height of $5cm$. Its volume is:

• A. $100c{m}^3$
• B. $1000c{m}^3$
• C. $500c{m}^3$
• D. $1000c{m}^2$

Answer 1

The correct option is B $1000c{m}^3$

Given:
Length, $l=20cm$
Breadth, $b=10cm$
Height, $h=5cm$

Volume is given by:
$V=lbh$
$V=20cm\times 10cm\times 5cm$
$V=1000c{m}^3$
