A right rectangular prism is packed with cubes of side length Fraction 1 over 3 inch. If the prism is packed with 6 cubes along the length, 4 cubes along the width, and 8 cubes along the height, what is the volume of the prism?


Fraction 7 and 1 over 9 cubic inches


Fraction 17 and 7 over 9 cubic inches


16 cubic inches


192 cubic inches

Verified Answer :

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

Answer:

The correct answer is :7 and 1 over 9 cubic inches  that is \(7\frac{1}{9} inches^3\).

Step-by-step explanation:

Length of the cube = a =\(\frac{1}{3} inch\)

Volume of the cube = V

V= \(a^3\) = \((\frac{1}{3} inch)^3=\frac{1}{27} inch^3\)

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

\(= 192\times \frac{1}{27} inch^3=7\frac{1}{9} inches^3\)
