Question

If the side of an open cubical box is 3.25 cm,how many litres of air does it contain?

Answer 1

The litres of air present in cubical box will be equal to volume of cubical box

we know volume of cubical box = Side³

Given Side = 3.25 cm

So volume = Side³ = 3.25³ cm³

Volume = 3.25 * 3.25 * 3.25 cm³

Volume = 34.3281 cm³

We know 1 litre = 1000 cm³

1000 cm³ = 1 litre

1 cm³ = 1/1000 litre

34.3281 cm³ = 34.3281/1000 = .0343 litre

Volume of air in open cubical box equal to .0343 litre
