Question

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

Answer 1

Given a cuboid

long $=30cm=$ length

wide $=25cm=$ breadth (width)

volume $=4.5liters=4.5\times 1000$

$=4500cm$

We have to find height

volume $=$ length $\times$ breadth $\times$ height

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

$\frac{4500cm}{750cm}=$ height

height $=6cm$
