find the surface area of a rectangular prism in rust

To find the surface area of a rectangular prism, we need to calculate the area of each face and then add them together. We can use the following Rust code to calculate the surface area:

main.rs
fn main() {
    let length = 10.0;
    let width = 5.0;
    let height = 3.0;

    let area = 2.0 * (length * width + length * height + width * height);

    println!("The surface area of the rectangular prism is: {}", area);
}

In this code, we first define the length, width and height of the rectangular prism. We then use the formula 2lw + 2lh + 2wh to calculate the surface area and store it in the area variable. Finally, we print the result using the println! macro.

You can replace the values of length, width and height with your own values to find the surface area of any rectangular prism.
