# Java Program to Find the Volume and Surface Area of Cuboid

• Difficulty Level : Basic
• Last Updated : 05 Sep, 2022

A Cuboid is a 3-dimensional box-like figure represented in the 3-dimensional plane. A cuboid has 6 rectangle-shaped faces. Each face meets another face at 90 degrees each. Three sides of cuboid meet at the same vertex. Since it is made up of 6 rectangle faces, it has length, width and height of different dimension. Given the dimensions of the cuboid, find the Surface area and Volume of a cuboid. The formula’s to calculate the area and volume are given below.

Examples:

```Input : 20 15 10
Output : Surface Area = 1300
Volume = 3000

Input : 30 5 10
Output : Surface Area = 1000
Volume = 1500```

Formulas:

Volume = length * breadth * height

Surface Area of Cuboid = 2(length * breadth + breadth * height + height * length)

Approach :

• Given the dimensions of the cone, say length L, height H and breadth B of a cuboid.
• Calculate Volume and Surface Area

Example 1:

## Java

 `// Java Program to Find the Volume and Surface Area of``// Cuboids` `import` `java.io.*;` `class` `GFG {``    ``public` `static` `void` `main(String[] args)``    ``{``        ``// specify L,B and H``        ``double` `L = ``20``, B = ``15``, H = ``10``;``      ` `        ``// calculate SurfaceArea``        ``double` `SurfaceArea = ``2` `* (L * B + B * H + H * L);``      ` `        ``// calculate Volume``        ``double` `Volume = L * B * H;``      ` `        ``System.out.println(``            ``"The Surface area of cuboid is : "``            ``+ SurfaceArea);``      ` `        ``System.out.println(``"The Volume of the cuboid is : "``                           ``+ Volume);``    ``}``}`

Output

```The Surface area of cuboid is : 1300.0
The Volume of the cuboid is : 3000.0```

Time Complexity: O(1) as it is doing constant operations

Space Complexity: O(1)

Example 2:

## Java

 `import` `java.io.*;` `class` `GFG {``    ``public` `static` `void` `main(String[] args)``    ``{``        ``// specify L,B and H``        ``double` `L = ``30``, B = ``5``, H = ``10``;``      ` `        ``// calculate SurfaceArea``        ``double` `SurfaceArea = ``2` `* (L * B + B * H + H * L);``      ` `        ``// calculate Volume``        ``double` `Volume = L * B * H;``      ` `        ``System.out.println(``            ``"The Surface area of cuboid is : "``            ``+ SurfaceArea);``      ` `        ``System.out.println(``"The Volume of the cuboid is : "``                           ``+ Volume);``    ``}``}`

Output

```The Surface area of cuboid is : 1000.0
The Volume of the cuboid is : 1500.0```

Time Complexity: O(1) as constant operations are performed

Space Complexity: O(1) since using constant variables
