Answer:

The correct answer is :7 and 1 over 9 cubic inches that is
7(1)/(9) inches^3.

Explanation:

Length of the cube = a =
(1)/(3) inch

Volume of the cube = V

V=
a^3 =
((1)/(3) inch)^3=(1)/(27) inch^3

Right rectangular prism is packed with these cubes:

Number of cubes placed along the length = 6 cubes

Number of cubes placed along the width = 4 cubes

Number of cubes placed along the height = 8 cubes

Total number of cubes in the right rectangular prism = 6 × 4 × 8 = 192 cubes

Volume of the right rectangular prism :

Number of cubes × Volume of cube


= 192* (1)/(27) inch^3=7(1)/(9) inches^3

Length of prism = 1/3 x 6 = 2 inches
Width of prism = 1/3 x 4 = 4/3 inches
Height of prism = 1/3 x 8 = 8/3 inches

Volume of prism = 2 x 4/3 x 8/3 = 7 1/9 cubic inches
