You  can make a function named  VolumeOfCuboid  which takes parameters  L,  B  and H. Now the
                 function will look like:
                 VolumeOfCuboid (L, B, H)

                 {
                 return L * B * H
                 }

                 You only need to provide the value of:
                    Length (L)
                    Breadth (B)

                    Height (H)
                 Thus  the  aria les accepted  y a  unction to per orm the set o  tas s defined in its  ody are called
                 function parameters.

                 Returning Value from a Function

                 The main purpose of using functions is to get rid of the repetitive block of code. So, when an operation
                 is performed inside a function it gives back a value, which can be used later in the program to get the
                 results, which makes a function more useful.
                 Consider  the previous  example  in which  you  have calculated  the  volume  of a cuboid, the
                 VolumeOfCuboid did not return any value. But when the program executes, the volume of cube gets
                 calculated and assigned the variable “volume” to it, then it returns a value. However, it becomes
                 useless if the function doesn’t return.

                 To implement return function in the volume of a cuboid.
                 Step 1   The code for calculating the volume of cuboid is:















                 Step 2    Click on the ‘Functions’, select ‘return’ block. Drag and place it in the function block and
                          add the variable ‘volume’ to its text area as shown below
