Step 4:  From the  ‘Variables’ select ‘set cube
                            to 0’ block. Drag ‘set cube to 0’, and

                            drop  it to the ‘function  ’Cube  of  a
                            number’block.  From the ‘Math’  block,
                            select ‘multiplication’ block two times.

                            From  ‘Variables’ select variable ‘num1’ three times. Drag variable ‘num1’ and
                            drop them to ‘multiply’ block. Now, drag the multiplication block to ‘0’ of ‘set
                            cube to 0’ block.

                  Step 5:  From ‘Function’ select ‘return’ block, and drag the variable ‘cube’ and drop it on the
                            ‘0’ of ‘return’ block. Drag and drop the ‘return’ block to ‘function- Cube of a number’.

                  Step 6:  In the same way, create a function ‘Square of a number’.














                  Step 7:  From the ‘Function’ select ‘call Square of a number’ and ‘call Cube of a number‘,
                            drop them to ‘set var1 and set var2’. In ‘set var3’, drag and drop addition block

                            and in ‘0’ drag the variable ‘var1’ and ‘var2’.















                  Step 8:  From ‘Game’, select ‘splash’ block.  Click on ‘Advanced’, select ‘Text’, and then click
                            on ‘join’ block. Drag the ‘join’ block and drop it to the ‘splash’ block.

                  Step 9:  Type the message ‘Output is:’ in ‘hello’ and in ‘world’ drag the variable ‘var3’, and
                            drop it in a ‘join’ block.
