Formulae. Please help

What is your question? Where are you stuck? It really is hard for someone to help you if you do not state where you are stuck.
 
I am stuck on both tbh. I came up with. X=lmh-dy -4cf for 1st question. Which doesn't make sense.
 
How many walls are in the room?

What are the dimensions of each wall?

How much area do the walls take up if there were no windows all doors?

How much area do the door and windows take up?

How does this help you?

This can't be since the units are all meters so h meters* l meters * m meters will be him meters^3. But each wall is 2-dimensional. It may be say 5meters by 6 meters which is 30 meters^2 NOT m^3

All can you only respond to one of your post, not both. Please
