Question

A 2-litre bottle is half-filled with water. How much more water must be added to fill up the bottle completely? With explanation please.
a)$\frac{1}{3}cm^{2}$
b)100cm²
c)500cm²
d)1000cm²

Answer 1

The bottle can contain 2 litres

1/2 of the bottle = 2× (1/2) = 1 litre

Now the bottle has 1 litre of water

To fill up the bottle, we should add = 2-1 = 1 litre

1 litre = 1000 cm^(3)

Hope this will help.....
