Dave made two boxes. The side of the second box are each 1/3 of the sides of the first box.

How are the volumes of the two boxes related?
A. The volume of the second box is 1/36 of the volume of the first box
B. The volume of the second box is 1/27 of the volume of the first box
C. The volume of the second box is 1/9 of the volume of the first box
D. The volume of the second box is 1/3 of the volume of the first box

To determine how the volumes of the two boxes are related, we can compare the volumes based on the dimensions given.

Let the side length of the first box be \( s \). The volume \( V_1 \) of the first box is given by the formula for the volume of a cube:

\[ V_1 = s^3 \]

The sides of the second box are each \(\frac{1}{3}\) of the sides of the first box. Thus, the side length of the second box is

\[ s_2 = \frac{1}{3}s. \]

The volume \( V_2 \) of the second box is then:

\[ V_2 = \left(\frac{1}{3}s\right)^3 = \frac{1}{3^3}s^3 = \frac{1}{27}s^3. \]

Now, we can compare the two volumes:

\[ \frac{V_2}{V_1} = \frac{\frac{1}{27}s^3}{s^3} = \frac{1}{27}. \]

Thus, the volume of the second box is \(\frac{1}{27}\) of the volume of the first box.

Therefore, the correct answer is:

B. The volume of the second box is \(\frac{1}{27}\) of the volume of the first box.
