1 answer

To calculate the volume of the box, you can use the formula for the volume of a rectangular prism:

\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \]

Given:

  • Length = 2 feet
  • Width = \( \frac{1}{4} \) foot
  • Height = \( 1 \frac{1}{5} \) feet

First, convert the height from a mixed number to an improper fraction:

\[ 1 \frac{1}{5} = \frac{5}{5} + \frac{1}{5} = \frac{6}{5} \]

Now substitute the values into the volume formula:

\[ \text{Volume} = 2 \times \frac{1}{4} \times \frac{6}{5} \]

First, calculate \( 2 \times \frac{1}{4} \):

\[ 2 \times \frac{1}{4} = \frac{2}{4} = \frac{1}{2} \]

Now multiply \( \frac{1}{2} \) by \( \frac{6}{5} \):

\[ \frac{1}{2} \times \frac{6}{5} = \frac{6}{10} = \frac{3}{5} \]

Thus, the volume of the box is:

\[ \frac{3}{5} \text{ cubic feet} \]

Among the response options provided, the correct answer is 3/5 cubic foot.
