# Python | Percentage increase in the total surface area of the cuboid

Given a cuboid of length L, breadth B and Height H, the task is to find percentage increase in the total surface area of the cuboid if length, breadth and height are increased by fixed percentages.

Examples:

```Input :
L = 20, B = 30, H = 50, l = 10 %, b = 12 %, h = 15 %
Output :
26.97 %

Input :
L = 40, B = 60, H = 15, l = 5 %, b = 7 %, h = 12 %
Output :
14.88 %
```

Code : Python code to find the increase in the total surface area of the cuboid.

 `# Function to return the percentage increase  ` `# in the total surface area of the cuboid  ` `# Total surface area of a cuboid = 2(L * B) + (L * H) + (B * H) ` `def` `increaseIntsa(L, B, H, l, b, h): ` `    ``oldsurfacearea ``=` `2``*``((L ``*` `B) ``+` `(L ``*` `H) ``+` `(B ``*` `H)) ` `    ``newsurfacearea ``=` `2``*``((L ``+` `(L ``*` `l ``*` `0.01``))``*``(B ``+` `(B ``*` `b``*``0.01``)) ``+`  `                        ``(L ``+` `(L ``*` `l ``*` `0.01``))``*``(H ``+` `(H ``*` `h``*``0.01``)) ``+` `                        ``(B ``+` `(B ``*` `b ``*` `0.01``))``*``(H ``+` `(H ``*` `h``*``0.01``))) ` `    ``increase ``=` `(newsurfacearea ``-` `oldsurfacearea) ` `    ``increasepercent ``=` `(increase ``/` `oldsurfacearea) ``*` `100` `    ``return``(increasepercent) ` ` `  `# Cuboid dimnesions ` `L ``=` `20` `B ``=` `30` `H ``=` `50` ` `  `# percentage increase ` `l ``=` `10` `b ``=` `12` `h ``=` `15` `print``(increaseIntsa(L, B, H, l, b, h), ``"%"``)  `

Output :

`26.974193548387092 %`
