Question

A water container can hold $40$ litres of water. Number of ice cubes of side $5cm$ that can be filled into the container is ____

Answer 1

$1$ litre $=1000c{m}^3$

$40$ litres $=40000c{m}^3$

Volume of each cube $=5^{3}c{m}^3$

So, number of cubes that can be fitted $=\frac{\text{Total volume of the container}}{\text{Volume of the cubes}}=\frac{40000}{5\times 5\times 5}=320$
