Answer:

512 1/2 inch cubes

Step-by-step 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.
