长、宽、高按固定百分比增加时长方体体积的百分比增加
原文:https://www . geesforgeks . org/如果长宽高按固定百分比增加，长方体的体积增加百分比/
给定一个长方体和三个整数 L 、 B 和 H 。如果长方体的长度增加 L% ，宽度增加 B% ，高度增加 H% 。任务是找出长方体体积增加的百分比。 示例:
输入: L = 50，B = 20，H = 10 输出: 98% 输入: L = 10，B = 20，H = 30 输出: 71.6%
逼近:假设长方体原来的长、宽、高分别为 l 、 b 和 h 。现在，增加的长度将是 (l + ((L * l) / 100)) 即增加的长度= l * (1 + (L / 100)) 。同样，增加的宽度和高度将是增加的宽度= b * (1 + (B / 100)) 和增加的高度= h * (1 + (H / 100)) 。 现在，计算原始 ol = l * b * h 和增加的体积=增加的长度增加的读数增加的高度。 并且，增加的百分比可以找到为((增加的体积–原始体积)/原始体积)* 100
(((L (1+(L/100)) B (1+(B/100))H (1+(H/100)))–(L * B * H))/(L * B * H)) 100 ((L * B * H (1+(L/100))(1+(B/100))(H/100))–1)/(L * B * H)) 100 ((1)*
以下是上述方法的实现:
C++
// C++ implementation of the approach
#include <bits/stdc++.h>
using namespace std;
// Function to return the percentage increase
// in the volume of the cuboid
double increaseInVol(double l, double b, double h)
{
double percentInc = (1 + (l / 100))
* (1 + (b / 100))
* (1 + (h / 100));
percentInc -= 1;
percentInc *= 100;
return percentInc;
}
// Driver code
int main()
{
double l = 50, b = 20, h = 10;
cout << increaseInVol(l, b, h) << "%";
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// Java implementation of the approach
class GFG
{
// Function to return the percentage increase
// in the volume of the cuboid
static double increaseInVol(double l,
double b,
double h)
{
double percentInc = (1 + (l / 100)) *
(1 + (b / 100)) *
(1 + (h / 100));
percentInc -= 1;
percentInc *= 100;
return percentInc;
}
// Driver code
public static void main(String[] args)
{
double l = 50, b = 20, h = 10;
System.out.println(increaseInVol(l, b, h) + "%");
}
}

Python 3
# Python3 implementation of the approach
# Function to return the percentage increase
# in the volume of the cuboid
def increaseInVol(l, b, h):
percentInc = ((1 + (l / 100)) *
(1 + (b / 100)) *
(1 + (h / 100)))
percentInc -= 1
percentInc *= 100
return percentInc
# Driver code
l = 50
b = 20
h = 10
print(increaseInVol(l, b, h), "%")

C
// C# implementation of the approach
using System;
class GFG
{
// Function to return the percentage increase
// in the volume of the cuboid
static double increaseInVol(double l,
double b,
double h)
{
double percentInc = (1 + (l / 100)) *
(1 + (b / 100)) *
(1 + (h / 100));
percentInc -= 1;
percentInc *= 100;
return percentInc;
}
// Driver code
public static void Main()
{
double l = 50, b = 20, h = 10;
Console.WriteLine(increaseInVol(l, b, h) + "%");
}
}
// This code is contributed by Code_Mech
java 描述语言
<script>
// Javascript implementation of the approach
// Function to return the percentage increase
// in the volume of the cuboid
function increaseInVol(l, b, h)
{
let percentInc = (1 + (l / 100))
* (1 + (b / 100))
* (1 + (h / 100));
percentInc -= 1;
percentInc *= 100;
return percentInc;
}
// Driver code
let l = 50, b = 20, h = 10;
document.write(increaseInVol(l, b, h) + "%");
</script>
Output:
98%
