Please create a Hierarchy chart for the following:

A painting company has determined that for every $300$ square feet of wall space, one gallon of paint and eight hours of labour will be required. The company charges $$20$ per hour for labour.

Design a modular algorithm that asks the user to enter the following information:

$$ The height and width of room walls in feet or inches

$$ The height and width of doors and windows in feet or inches

$$ The number of walls, doors and windows

$$ The price of the paint per gallon

Calculate the square feet of wall space to be painted. Calculate the square feet of doors and windows and subtract those areas from room total because we use a different paint on the windows and doors. The program should display the following data:

$1.$ The number of gallons of paint required

$2.$ The hours of labour required

$3.$ The cost of the paint

$4.$ The labour charges

$5.$ The total cost of the paint job

Note: i don't need the javacode $-$ only the chart
