find the volume of a rectangular prism in rust

To find the volume of a rectangular prism in Rust, we can create a function that takes the length, width, and height of the prism and returns the volume.

main.rs
fn rectangular_prism_volume(length: f64, width: f64, height: f64) -> f64 {
    let volume = length * width * height;
    volume
}

In this function, we first calculate the volume by multiplying the length, width, and height. Then we return the volume as a floating point number (f64).

We can then call this function and pass in the dimensions of the prism as arguments. For example, if we have a rectangular prism with a length of 5, a width of 3, and a height of 2, we can find the volume like this:

main.rs
let length = 5.0;
let width = 3.0;
let height = 2.0;

let volume = rectangular_prism_volume(length, width, height);

println!("The volume of the rectangular prism is {} cubic units.", volume);

This will output:

main.rs
The volume of the rectangular prism is 30 cubic units.
