We are given the volume of a rectangular prism as 19.44 cubic meters. The dimensions of the prism are 3 meters, 2.7 meters, and $r$ meters. We need to find the value of $r$.

1. Problem Description

We are given the volume of a rectangular prism as 19.44 cubic meters. The dimensions of the prism are 3 meters, 2.7 meters, and $r$ meters. We need to find the value of $r$.

2. Solution Steps

The formula for the volume of a rectangular prism is:

$Volume = length \times width \times height$

In this case, the volume is given as 19.44 cubic meters, and the dimensions are 3 meters, 2.7 meters, and $r$ meters.

So, we have:

$19.44 = 3 \times 2.7 \times r$

$19.44 = 8.1 \times r$

To find the value of $r$, we need to divide both sides of the equation by 8.1:

$r = \frac{19.44}{8.1}$

$r = 2.4$

3. Final Answer

The value of $r$ is 2.4 meters.
