MOM, I am trying to find the surface area of my room to know how much paint we need. Do you think you know how to get the surface area?
If you want to find the surface area of your room you need to do certain steps to find out.
Sure, the first step in finding your room’s surface area is by knowing the sum of all the surface of your room.
I don’t really remember the steps, can you remind them to me
Mom, my room is a simple rectangular prism, so if I’m not wrong I need to measure the length, width and the height only once.
Correct! Then don’t forget to use the surface area formula minus the part of your carpet.
Just to make sure, the formula is 2lh+2lw+2wh but you want me to take out the carpet area 2lh+1lw+2wh?
Yes, this will give you the surface area that needs to be painted with the ceiling to find what we need to purchase.
2(12in x14in)+1(12in x10in)+2(10in x14in) will be 336 + 120 + 280 for a total of 736 in square. Now, I know the amount of surface area that I need to cover with paint.
