Program/Source Code:

The source code to calculate the surface area, volume, and space diagonal of cuboids is given below. The given program is compiled and executed successfully.

// Rust program to calculate the surface area, 
// volume, and space diagonal of cuboids

use std::io;

fn main() 
{
    let mut height:f32  =0.0;
    let mut width:f32   =0.0;
    let mut length:f32  =0.0;
    
    let mut area:f32    =0.0;
    let mut volume:f32  =0.0;
    let mut diagonal:f32=0.0;
      
    let mut input1 = String::new();
    let mut input2 = String::new();
    let mut input3 = String::new();
    
    println!("Enter height: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    height = input1.trim().parse().expect("Not a valid number");
    
    println!("Enter width: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    width = input2.trim().parse().expect("Not a valid number");
    
    println!("Enter length: ");
    io::stdin().read_line(&mut input3).expect("Not a valid string");
    length = input3.trim().parse().expect("Not a valid number");
    
    diagonal =(width * width).sqrt() + (length * length) + (height * height);
    area     = 2.0 * (width * length) + (length * height) + (height * width);
    volume   = width * length * height;

    println!("Volume of Cuboids is		  : {}", volume);
    println!("Surface area of Cuboids is  : {}", area);
    println!("Space diagonal of Cuboids is: {}", diagonal);
}

Output:

Enter height: 
10.2
Enter width: 
14.7
Enter length: 
16.5
Volume of Cuboids is              : 2474.01
Surface area of Cuboids is  : 803.34
Space diagonal of Cuboids is: 390.99

Explanation:

Here, we read the height, width, and length from the user. Then we calculated the surface area, volume, and space diagonal and printed the result.
