Cuboid:

A Cuboid is a three-dimensional object made up of six Rectangles. All of the opposing faces (Top and Bottom) are the same.

A Cuboid’s Surface Area : 

The Total Surface Area of a Cuboid is the sum of the areas of the Cuboid’s six rectangles. If we know the Cuboid’s length, width, and height, we can use the formula to calculate its Total Surface Area:

Top and bottom surface area = lw + lw = 2lw

Front and back surface area = lh + lh = 2lh

Both sides’ area = wh + wh = 2wh

A Cuboid’s Total Surface Area is the sum of its six faces. So, in order to calculate the final Surface Area, we must add all of these areas together.

A Cuboid’s Total Surface Area = 2lw + 2lh + 2wh

It is the same as:

Formula for Surface Area of a cuboid = 2 (lw + lh + wh).

A Cuboid’s Volume :
Volume is the amount of space inside the Cuboid. If we know the Cuboid’s length, width, and height, we can use the following formula to calculate its volume:

Cuboid Volume = Length * Breadth * Height

A Cuboid’s Volume = lbh

A Cuboid’s Lateral Surface Area = 2h (l + w).

Given the length, width, and height of a cuboid, the task is to calculate the volume and surface of a given cuboid.

Examples:

Example 1:

Input:

Given length = 1
Given width = 2

The given surface Area of a Cuboid with given length,width,height[ 1 2 3 ]= 22.000
The given volume of a Cuboid with given length,width,height[ 1 2 3 ]= 6.000
The given lateral surface Area of a Cuboid with given length,width,height[ 1 2 3 ]= 18.000

The given volume of a Cuboid with given length,width,height[ 2.5 5.0 3.0 ]= 37.500
The given lateral surface Area of a Cuboid with given length,width,height[ 2.5 5.0 3.0 ]= 45.000
