Side of Cube = 12cm
=> Volume of cube = side^3
Now this cube is cut into 8 new cubes of equal volumes,
=> 12^3÷8 will be the volume of one cube .
:• Volume of one small cube = 216 cm^3
As we know volume of cube is side^3
=> Side of the smaller cubes would be 3√216 = 6
:• Side of the new smaller cubes would be 6cm.
