可内接在正圆柱体内的最大立方体
这里给出的是一个高度为 h 半径为 r 的右圆柱体。任务是找到最大立方体的体积，可以在里面刻字。 示例 :
Input: h = 3, r = 2
Output: volume = 27
Input: h = 5, r = 4
Output: volume = 125
接近:从图中可以清楚的了解到立方体的边=圆柱体的高度。 所以，卷= (height)^3 以下是上述方法的实施:
C++
// C++ Program to find the biggest cube
// inscribed within a right circular cylinder
#include <bits/stdc++.h>
using namespace std;
// Function to find the volume of the cube
float cube(float h, float r)
{
// height and radius cannot be negative
if (h < 0 && r < 0)
return -1;
// volume of the cube
float a = pow(h, 3);
return a;
}
// Driver code
int main()
{
float h = 5, r = 4;
cout << cube(h, r) << endl;
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// Java Program to find the biggest cube

class Solution
{
// Function to find the volume of the cube
static float cube(float h, float r)
{
// height and radius cannot be negative
if (h < 0 && r < 0)
return -1;
// volume of the cube
float a = (float)Math.pow(h, 3);
return a;
}
// Driver code
public static void main(String args[])
{
float h = 5, r = 4;
System.out.println( cube(h, r) );
}
}
