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

Given height, width, and length, we have to calculate the surface area, volume, and space diagonal of cuboids using Rust program.
Submitted by Nidhi, on September 30, 2021

Problem Solution:

Here, we will read the height, width, length from the user. Then we will calculate the surface area, volume, and space diagonal of cuboids and print the result.

The surface area of cuboids:

A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. Consider that the length is l, width is w, and height is h of the prism and then the formula to calculate the Surface area of cuboids will be: 2lw + 2lh + 2hw

Volume of cuboids:

The formula to calculate the volume of cuboids (V) = whl

Space diagonal of cuboids: √(l2 + b2 +h2)

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: ");
height = input1.trim().parse().expect("Not a valid number");

println!("Enter width: ");
width = input2.trim().parse().expect("Not a valid number");

println!("Enter length: ");
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.
