Question

How many litres of water can a cube of side 10 cm hold?

• A. 1

Answer 1

The correct option is A 1
The amount of space that an object takes up is its volume.

Volume of a cube is given by
$V=\text{side}\times \text{side}\times \text{side}.$

A cube of side 10 cm has a volume of
$10\text{cm}\times 10\text{cm}\times 10\text{cm}=1000{\text{cm}}^3.$


We know that $1\text{L}=1000\text{mL}$ and $1{\text{cm}}^3=1\text{mL}.$

$\therefore 1\text{L}=1000{\text{cm}}^3$

Thus, a cube of side 10 cm can hold 1 litre of water.
