Question

How many cubes each of side 0.5 cm are required to build a cube of volume of $8c{m}^3$?

Answer 1

Volume of a cube $=(Side{)}^3$
$\because$ Side of cube = 0.5 cm
$\therefore$ Volume of the cube $=(0.5{)}^3=0.125c{m}^3$

The number of cubes required to make volume of $8c{m}^3$ cube
$=\frac{8}{0.125}=\frac{8000}{125}=64cubes$
