The problem states that the volume of a rectangular prism is 25.76 cubic feet. The dimensions of the rectangular prism are 2.8 ft, 2 ft, and $y$ ft. We need to find the value of $y$.

1. Problem Description

The problem states that the volume of a rectangular prism is 25.76 cubic feet. The dimensions of the rectangular prism are 2.8 ft, 2 ft, and $y$ ft. We need to find the value of $y$.

2. Solution Steps

The volume of a rectangular prism is given by the formula:

$Volume = length \times width \times height$

In this case, the volume is 25.76 cubic feet, the length is 2.8 ft, the width is $y$ ft, and the height is 2 ft.

So, we have:

$25.76 = 2.8 \times y \times 2$

$25.76 = 5.6 \times y$

To find the value of $y$, we need to divide both sides of the equation by 5.6:

$y = \frac{25.76}{5.6}$

$y = 4.6$

3. Final Answer

The value of $y$ is 4.6 feet.
