Question

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

Answer 1

we know,

1 litre = 1000cm³
4.5 litres = 4.5 × 1000 cm³
volume = 4500 cm³

Volume = length × breadth × height

$4500 = 30 \times 25 \times height$
$4500 = 750 \times height$

$height \: = \frac{4500}{750}$
height = 6

therefore,
height is 6cm
