Question

A vessel in the shape of a cuboid is 30 cm long and 25 cm wide. What should be its height to hold 4.5 litres of water ?

Answer 1

$\text{Length of a cuboidal vessel (l)}=30\text{cm}$
$\text{breadth}\left(b\right)=25\text{cm}$
$\text{height}\left(h\right)=?$
$\text{The volume of water m a cuboidal vessel}=4.5\text{Litres}$
$=4.5\times 1000{\text{cm}}^3$
$=4500{\text{cm}}^3$
$\therefore l\times b\times h=4500$
$\Rightarrow 30\times 25\times h=4500$
$\Rightarrow h=\frac{4500}{30\times 25}$
$\therefore h=6\text{cm}$
$\text{Height of the vessel (h) = 6 cm}$
