Rust program to calculate the area of Cube

Program/Source Code:

The source code to calculate the area of Cube is given below. The given program is compiled and executed successfully.

// Rust program to calculate the area of Cube

use std::io;

fn main() 
{
    let mut side:f32    =0.0;
    let mut area:f32    =0.0;
    
    let mut input = String::new();
         
    println!("Enter length of side: ");
    io::stdin().read_line(&mut input).expect("Not a valid string");
    side = input.trim().parse().expect("Not a valid number");
    
    area = 6.0 * side * side;
    
    println!("Area of Cube is: {}", area);
}

Output:

Enter length of side: 
2.67
Area of Cube is: 42.773403

Explanation:

Here, we read the length of the side from the user. Then we calculated the area of the Cube and printed the result.
