Eight 4 inch cubes are needed to build and 8 inch cube.
u draw a cube and count the vertices... a cube has 8 vertices
8*8*8 = 512 cubic inches.
Entire surface area: 6*8*8 = 384 square inches
The volume of the little cube is 23 = 8 cubic inches so the density of the material is 8/20 = 0.4 grams per cubic inch.The volume of the large cube is 83 = 512 cubic inches, so the mass (not the weight) is 512*0.4 = 128 grams.
