Rubik cube

The volume of the Rubik's cube below is 216 cm³. Find the volume of the each smaller cube.

Sol: Given that the volume of the Rubik cube is 216 cm³.

∴ Length of one edge of Rubik cube	=
	=	6 cm

In Rubik cube, 3 smaller cubes make one edge.

∴ Length of the edge of smaller cube	=
	=	2 cm
Volume of the smaller cube	=	2³
	=	8 cm³
Alternate method:
Number of smaller cubes	=	27
Volume of each smaller cube	=	216/27
	=	8 cm³
