kotlin 查找id

A cube has 6 square faces, if edges length is side. Then the area of each square is side², thus, the area of cube will be 6*sise².

如果边的长度为side ，则一个立方体有6个正方形的面。 那么每个正方形的面积是边² ，因此，立方体的面积将是6 * sise ² 。

Given the value of side of the cube, we have to find its area.

给定立方体的side值，我们必须找到它的面积。

Example:

例：

    Input:
    side = 5

    Output:
    Area of cube = 150.0

程序在Kotlin中查找立方体的区域 (Program to find area of a cube 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 side
    print("Enter Side of Cube : ")
    val side = scanner.nextDouble()

    //Cube Surface Area
    val areaCube = 6*Math.pow(side, 2.toDouble())

    //Print Area
    println("Cube Surface Area on Side ($side) is :$areaCube")
}

Output

输出量

Run 1:
Enter Side of Cube : 5
Cube Surface Area on Side (5.0) is :150.0
---
Run 2:
Enter Side of Cube : 12
Cube Surface Area on Side (12.0) is :864.0
