Question

A rectangular container measuring 20cm x 30cm x 50cm is filled with water. What is the mass of this volume of water in kilograms? A. 30 kg B. 30,000 kg C. 30 milligrams D. 30,000 lbs

Answer 1

A. 30 kg

Step-by-step explanation:

As we know that,

`1 litre=1000cm^(3)`

And 1 litre is equivalent to 1kg.

Given that, The volume of the rectangular container is,

`V=20cm* 30cm* 50cm\\V=30000cm^(3)`

And this volume will be equal to
`V=30000cm^(3)=30litres`

And this litres in kg will be equal to,

`V=30litres=30 kg`

Therefore the mass of this volume of water is 30 kg.
