# Kotlin program to find surface area of a cuboid

Kotlin | Surface area of a cuboid: Here, we are implementing a Kotlin program to find surface area of a cuboid.
Submitted by IncludeHelp, on May 08, 2020

A cuboid is a three-dimensional figure which is bounded by 6 rectangular planes, they have different magnitude of length, width and height.

Formula to find surface area of a cuboid: 2( length*width + length*height + height*width)

Given length, width and height, we have to find surface area of a cuboid.

Example:

```    Input:
length = 3
width  = 4
height = 6

Output:
Surface Area of Cuboid is :108.0
```

### Program to find surface area of a cuboid in Kotlin

```package com.includehelp

import java.util.*

//Main Function , Entry point of Program
fun main(args: Array<String>) {

//Input Stream
val scanner = Scanner(System.`in`)

//Input Length of Cuboid
print("Enter Cuboid Length : ")
val length = scanner.nextDouble()

//Input Width of Cuboid
print("Enter Cuboid Width : ")
val width = scanner.nextDouble()

//Input height of Cuboid
print("Enter Cuboid Height : ")
val height = scanner.nextDouble()

//Calculate surface area of cuboid
val areaCuboid = 2*( length*width + length*height + height*width )

//Print surface area of cuboid
println("Surface Area of Cuboid is :\$areaCuboid")
}
```

Output

```Run 1:
Enter Cuboid Length : 3
Enter Cuboid Width : 4
Enter Cuboid Height : 6
Surface Area of Cuboid is :108.0
---
Run 2:
Enter Cuboid Length : 5
Enter Cuboid Width : 6
Enter Cuboid Height : 2
Surface Area of Cuboid is :104.0
```
