Answer:

512 1/2 cubes

Explanation:

The volume of the cube model : 4 x 4 x 4 = 64 cubic inches

1/2 x 1/2 x 1/2 = 1/8 - one 1/2 inch cube

64 / 1/8 = 512 1/2 inch cubes

Answer:

512 1/2 inch cubes

Explanation:

-In order to get 4 inches width, you will need 8 1/2 cubes (1/2 x 8 = 4)

-In order to get 4 inches height, you will need 8 1/2 cubes (1/2 x 8 = 4)

-In order to get 4 inches length, you will need 8 1/2 cubes (1/2 x 8 = 4)

8 length x 8 width x 8 height = 512 1/2 inch cubes to build a solid 4x4x4 inch cube.
